Hello All,I’m not sure why the textbox result in P10 doesn’t have a red box around it, while the one in P11 does.In P10In P11Regards,Sam 

Hi there ,To be honest I don't even know I need to multiple selective values in a matrix with selective values in another matrix . I used ( submatrix function ) however it didn't work :where m is a row number Here I want mathcad to multiple the first three values from both d and z Can you help me doing this ? the sheet is attached Thanks Yusra  

Hello Community,  Please find the mathcad file in the attached it was developed in PTC91.In the following after the symbolic evaluation the units are not simplifying, for instance Ohms*Faradsshould be seconds, and Farad * Voltage should be Columbs, but 2.After Q2 as assigned as the result after the integration, when I try to call on Q2 it cannot be found, can someone please explain? Thanks 

I'm using WRITECSV to write the contents of a matrix to a .CSV file. The WRITECSV function writes the contents with full precision, giving me numbers with 18 decimal places. I want to round the elements to a few decimal places. I wrote a function to do this, but it feels kind of clunky. Is there a native way to accomplish what I'm trying to do? I'm using Prime 11. 

Hello!!i am kind of new to the program and I have researched but still can not find the answer. I tried to create a solve block where I can get the final reult of a variable H_2 but it does not work.I upload a PDF of the problem. I believe is not difficult but perhaps I am missing something

Why doesn’t Mathcad Prime 11.0.1 no longer accept ASCII code [13] for carriage return (new line)?It appears to work in version 10.0.1 but not in 11.0.1. Is this true for everyone else or just me?I have both versions on the same computer--is there something I am missing?   

Hi there,I am trying to fetch the required gross concrete cross sectional area of an RCC column using the SYMBOLIC Solver function as shown below. But I could not figure out what is causing this abnormal output. Could someone kindly clarify this issue? I would be much obliged.   

The Mathcad rounding and truncation functions take the form function(z,y), where z may be complex but y must be real,   This is an unnecessary restriction and contravenes the Zen of Mathcad Rule 16.   This Mathcad Enhancement Proposal (MEP) extends the y argument to accept complex numbers.   Furthermore, the rounding and truncation functions operate only on scalars and vectors, not on matrices.  This is, again, an unnecessary restriction.   This MEP extends the truncation and rounding functions to accept matrix arguments.   The MEP further adds a function frac(z) that complements trunc by returning the fractional part of complex z; frac vectorizes over its arguments.    The MEP further extends the mod function to accept complex arguments; mod vectorizes over its arguments.       Stuart   Demonstration Mathcad Express 10 worksheet attached in support o

What I have here are two measured displacements over the same time with an equal interval of 1 second. Both oscillations tend to approach the resting asymptote, which is the same for both. The first one at the end of measurement didnt manage to approach, but the second did.For my task, I had to find periods and amplitudes of oscillations. To get periods, I simply used the difference between two interceptions of oscillation with asymptote via root() function. One of the arguments for this function is a guess points between which this interception should be met. For those points I pick local extremas (or peaks shortly). To get them, I need to know the first derivative of the oscillation function and look for the points where derivative becomes zero. But in my case, I have only empirical data, which I have to use to get proper constants a and w for the oscillation equation.Based on this, I created splines for both data sets, and started taking derivatives to find a slope.To get local

Hello All,Today I had P11 installed. It is worse than P9 and P10 combined in terms of speed. Also, I dont know why the Text Block, Text Box,  Image, Copy, and Paste  are greyed out.  Regards,Sam

Now that I have been forced onto Prime (changed employers, new install, 15 no longer for sale) I am really struggling with the keyboard shortcut for subscripting variable names. I get that there must be some good reason why PTC couldn't use . (period/dot) for it any more, but seriously "ctl -" is about the worst possible key combination they could have come up with instead - diagonal opposite corners of the keyboard making it a difficult one handed combo with lots of scope for mis-pressing one of the 2 keys and ending up creating some nightmare instead of the variable name you intended? I know word uses "ctrl +" and "ctrl shift +" (or something like that) for this, but the whole world doesn't have to follow microsoft's mistakes blindly. Please please please give us a single key shortcut for subscripts in variable names - is there somewhere we can start a petition of something to lobby for this? I am wasting hours and hours of time going back and re-typing my variable names because

I'm using MathCAD 9.0.0.0. I have 2 equations with 2 unknowns. I need solve for "DF" and "DG." I've attached 2 files. The file I need help with is "MET211_ProjectP2_Sections.mcdx." The other file "MET211_ProjectP2_Joints.mcdx" I attached as reference because I already solved for these variable using another method. Those of you familiar with Statics know there is the method of joints and the method of sections. Not that you need to know Statics or need the reference file to show me how problem solver works, I just added it incase it helps you understand my situation better. The way this was demonstrated was the demonstrator had a fancy calculator with a "problem solver" feature that allowed him to plug in 2 equations to solve for 2 unknowns. I don't have a fancy calculator. All I have is MathCAD, so I hope this can do it. Thank you,     Brent

HelloI am using advanced control text box with python to do conditional formatting. Unfortunately if the variable is undefined I cannot reset the formatting to warn the user something is wrong with the control which results in previous value being displayed. Is there any way to to change the text string/background color  in case any variable is undefined?My code below:def TextBoxEvent_Start():# TODO: Add your code here pass def TextBoxEvent_Exec(Inputs, Outputs): Outputs[0]['Value'] = TextBox.TextS = Inputs[0]['Value']A = Inputs[1]['Value'] stringText = TextBox.TextTextBox.Text = str(round(A/S,2)) if S>A:BackColor = TextBox.BackColorTextBox.BackColor = "#FF0000"else:BackColor = TextBox.BackColorTextBox.BackColor = "#92D050"pass def TextBoxEvent_Stop():# TODO: Add your code herepassThank youBest regards Michal

I have copied and pasting equations from Mathcad 15 to paste in Word document. The word document will be edited to be part of a book. the Editor told me that the quality of the equations was not good, that only had 96 dpi of resolution (I do not know what this mean). But for print, the quality of the equation, as seeing in the word document, has to be 300 dpi. Does anyone have idea how I can improve the quality of copying and pasting equations in word documents? thank you in advance,   Rogelio

This month’s challenge is a programming challenge inspired by Dijkstra’s algorithm, which finds the shortest path from a single source to all the other nodes in a network, based on weighting. In this scenario, we will use points in a 2D plot, where the weighting is the distance between the points.   Challenge 1: Known Points For the provided points, write a program to calculate the shortest path from the first node (5,5) to all other nodes, always choosing the shortest path from the current node. Feel free to use Mathcad's random number generator functions to make your own points instead. You can also start from a different point of your choosing if you so desire.   Challenge 2: Graphing Create a Chart Component or XY Plot that graphs this path.   Challenge 3: Advanced Inputs Incorporate advanced input controls to allow the user to change quantities such as the number of points or generate new points / path.   Challenge 4: 3D Can you write a program that performs t

When I find a new function and want to know what it does and what its arguments are, I go Resources > Help and enter the function name. Let's say I enter "augment". When I click search, I get dozens of hits and it takes me a while to find the one that actually explains how to use the function. Is there a more straightforward way to get right to the usage of the function? I'm using Prime 11.

Hi dear, I'm having trouble with the "for" loop when I create a function and try to graph a spectrum as a function of time.I have MathCAD version 11. It worked in the old version, but in this latest version, it shows me an error message stating that the variable T is not defined.Why is this happening? 

In mathcad Prime 1.0,is there any way to change the background color of the page?Thanks in advance.

Converting from Mathcad 14 file to Mathcad Prime 11.An error occurred when extracting and redefining a matrix by specifying a column.Changing the matrix column specification from a variable to a number does not cause an error.Why is the error occurring?

I am trying to fill a 1D array/vector with calculated scalar values. This works fine for a simple calculation; but for a more complicated calculation, it fills the vector with nested [1x1] arrays instead of scalars. I have tried to use Vectorize to fix this, but unsuccessfully.As an example, I define an array index i = -mf::mf. A simple function f_sub_i = f0 + df*i works fine to set up a vector of frequencies f with uniform step size df. But now I try a Gaussian function S_sub_i = e^{-[(f_sub_i -f0)/sigma]^2} , and I get a vector of nested [1x1] arrays instead of scalars. How can I get a vector of scalar values calculated by the formula for S_sub_i? I'm using MathCAD Prime 9.0.0.0

Does anybody know how Mathcad strings are encoded?   I've got a project on the back burner to look at Babylonian mathematics, including astronomical observations.  I'd like to convert between Arabic and Sumerian/Babylonian numbers and display them accordingly.  Unfortunately, whilst Unicode has code points for cuneiform numerals, I can't display them.   According to the Mathcad Prime 11 Help,   vec2str(v)—Converts a vector of UNICODE codes in v to a string. This function also works with zero-length strings, such as vec2str(0) = "". str2vec("S")—Converts a string S to a vector of UNICODE codes corresponding to the characters in S. This function also works with zero-length strings, such as str2vec("") = 0 v is a vector of integers representing UNICODE code points for any valid string character. Acceptable values are integers in the range 9, 10, 13, or 32 - 255. The mapping of codes to characte

Can anybody throw some light on the problem below when using min?   "System Error.  Entry point was not found."   I tried rearranging the definitions of pred and pushing min further down the functional chain, but to no avail.  Indeed, using IsFunction caused Mathcad to bang out.   max doesn't have this issue.  Nor do any of my redefinitions of min.   The problem occurs in both Mathcad Express 10 and Mathcad Express 11, even when only the definition of pred and the evaluation are present.  pred has a counterpart function, succ, and that too shows the problem.     Mathcad Express 10 worksheet attached and Exception log file attached.   Stuart  

Hi I need to subtract two different matrix . one has ( 7 rows, 2 column)  and the other has (5 rows , 1 column) I know the other own is shorter so the result should be the same number in the bigger matrix. like it treat the missing numbers as zeros Is that possible ? Thank you The sheet is attached
