hai all   how to extract specific raws from phi matrix , i am trying to solve this by using this equation in phi x

Hi,   Is it possible to include vertical/horizontal markers in the new chart components?  

Is there a Mathcad example in this forum that demonstrates a sensitivity analysis to determine the impact a variable has on the system. I searched the topics and found nothing. A shared example would be greatly appreciated. Thanks.

Has red equation one symbolic solution? See please the picture and the Mathcad 15 sheet in attach!

Hi,      I need a little help in implementing westgard (multirule QC) rules. There are 2 particular rules that I need some programming help with.   1. The 2 of 3_2s rule: Here I need to show that there is a violation if 2 of the 3 consecutive data points exceed a certain control limit (I don't care about the limit right now. I need to get the program going). 2.The 7T rule: In this case I need to show that there is a violation if 7 consecutive values trend in a particular direction.   I am attaching pics for the 2 rules. I am also uploading a demo worksheet.  Thanks in advance.

Hello all,I would like to assign the resulting vector to a variable but I do not know how to do it.Thank you all!

I wanted to create a table with text and numbers and then be able to sum the numbers.  Such as:     Item          Wt    Motor       100    Bearing      20    Mount       220   TotalWeight:= Sum Wt   But it is complaining that "Motor" etc. are undefined variables. I could created just a single column table to hold the weights and then align it against a series of text boxes but that does not feel right.   Thanks for your help,    Robin    

(Bicycle) chain is slung over two blocks. Given: r1, r2, x2, y2 (x1=y1=0) and L. Find: a form of the chain. Слабо?   If r1 and r2  -> 0 (or L -> infinity) we have this problem - see here.

Hello! I have started to use Mathcad a bit for circuit analysis with laplace transform. However, often the invlaplace does not give the output i expect. Am i doing something wrong?   I have attached a worksheet where i want to plot iL(t). However cant get it to work.   If i redefine the step function i am using (only using simple step) it works...... i need to be able to analyze step functions...   Would be great to get some input...   Best regards Kanka

Hello,   I'm currently performing Monte-Carlo-Simulations by using Mathcad Prime 4.0. When I change the number of events, I always get different values. Should an Monte-Carlo-Simulation not converge with a higher number of events to a certain value?    

Ultimately, I am trying to compare a plot developed on MathCAD to some experimental results that have been processed in MATLAB. Since I could not find a way to transfer data between the two, I thought to export both sets of data to Excel and plot them on top of each other there.  I had no issue exporting the data from MATLAB.  MathCAD Prime 4.0 however, is proving more difficult. The plot was created using a range and expressions that refer to that range.  I uploaded a sample code that demonstrates the issue. It appears that I cannot use the excel component to write an expression based on a range, though I can write the range itself.  Is there a way to transfer the values of my expression to a vector so that I can export to excel, without re-writing the previous expressions that lead up to my final expression? Thanks

Two parts to this question: 1. I am trying to determine what is the highest value of y will make the statement below read "GOOD". In this case I can pull that the value 20 would be the highest value, however this is part of a much larger program where the value of F`t changes, as well as other components in the f.t equation. Is there a way I can automatically pull the value "20"? 2. Similarly I would like to be able to pull the various combinations of y and p that would make the statement below read "GOOD".

M=r x F how to find vector r if F and M are defined Thanks in advance

Hi, How to write a program to find out consecutive values in a matrix.   Thanks, Aravind

Hi to all, i have been using mathcad for a while, but every now and then i get this issue even tho i make the same process every time, so i have a hard time finding my mistake. If somebody can help me out i will be greatly appreciated, thank you!   Mauricio B.

hai all  hwo to get the solution of the d , from the equation (k-w^2*m)*Phi

HAI ALL HOW TO MAKE A LOOP FOR THIS BELOW EQUATION , SINCE I WANT A SOLUTIONS FOR PHAY 

I'm trying to solve a system of simultaneous equations with a given value that changes. I attached a simplified worksheet to illustrate this. I used the variable 'I' to represent the position in the input matrix. I would like Mathcad to return the values of x0,y0, x1,y1, and x3,y3 all at one time for each value of Theta. I really don't know where to start on this. Any help would be appreciated.   Thanks

When I finished the installation of PTC Mathcad Express and got licence, it showed all blank like below How can I solve this problem?    

Hello,   can I perform a sensitivity analysis with Mathcad Prime 4.0? As a result I would like to know which parameter has the greatest effect on the Output. There are local and global sensitivity analysis. At local sensitivities, only one parameter is varied and all others are kept constant. Globals also indicate the interaction between the Parameters. Or maybe there is another oppurtunity. Thank you    

A long time ago I found by chance a way to get a popup where I could change cursor color and some other settings in Prime. Unfortunately I was not able to reproduce it (I was just poking around finding out how to achieve certain things via keyboard shortcuts, as the documentation for German keyboards is awfully wrong). Today I did the same (doc for shortcuts still is wrong) and was able to reproduce. As far as I remember the pop up window in the older Prime version offered more options to change.   So her it is: Pressing shift-ctrl-alt-Q or shift-altgr-Q at the same time opens a DebugPropertyWindow: I am not sure if this will work on other languages keyboards as well. If not, this information may help: On German keyboards pressing ctrl-alt-Q or altgr-Q creates the @ character. Not sure if there are other goodies hidden - go out and try 😉   EDIT: Sorry for the double post! When I searched the forum to see what I reported way back when I found out about this option first, I f

My Mathcad 15 student edition will not print in Windows 10 to any device including external printer or internal PDF converter, etc. Converting a file to prime 1 will allow printing to work from Prime 1. Reinstalled both Mathcad 15 and Prime 1 with no fix. Version M045 of Mathcad 15 did not help. Are there fixes available? I am running software on an HP Pavilion desktop. email: jerrybayles2013@outlook.com 08/09/2018

Hi all!   I'm finishing up my newest Mathcad but, I know longer want to use Mathcad's automatic calculation, I would much rather calculate the entire worksheet at one time at the top of the sheet (due to it's size) I'm hoping someone can explain how I could use a push button to achieve this? See the files I have attached (I've included what I'm sorta looking for on top).   Thanks!

Hi all - I have Prime 4.0, and have MC 15 installed on my computer as well, but the xmcd conversion button in Prime is still grayed out and not available.  Any suggestions? 

a:=[10nm, 20nm, 50nm, 100nm] b:=[20%, 15%, 10%, 5%]   lookup(10nm,a,b,"eq")=[20% 15% 10% 5%]   The problem is that equal (default), range and the rest of the modifiers take tolerance into consideration. Does anyone at PTC even use their own software? How can such an obvious bug, that would take 5 minutes to fix, still exist? How can you have a culture so toxic that it is easier to spend hours writing articles on getting around this bug, than fixing it.   Just add another modifier and set the tolerance value in the search to 0. This is incredibly frustrating to see such stupid bugs still around. I guess I may need to get better at yoga, so maybe I can see it as a feature from PTC's point of view.      Mathcad... The tool where you spend 80% of your time tracking down and working around bugs that would have taken developers 5 minutes to fix (fuming angry face)
