Mathcad

I would like to generate 2D curves in MathCAD that can be integrated into a 2D sketch in Solidworks for extrusions or extruded cuts. I would also like to generate 3D vectored formulas in MathCAD that can be projected onto a surface sketch in SolidWorks for extrusions or extruded cuts.

Hello. I really need help. Can somebody tell or show me, how to sort data from matrix (10x10) into one row from smallest number to largest? Or how to calculate frequency from this matrix into a row? I was looking information for hours, tried to sort data with excel, and tried to use sort function  in mathcad but that didin't work... 

Hi From MC15 help: 3D Plot Format Dialog Box (Appearance Tab) If there is more than one plot in the graph, these options are specific to each plot. Each plot can be filled with its own color, have its own lines drawn, among other options. The tabs labeled Plot 1, Plot 2, and so on, control the settings for individual plots. My question: How to assign one appearence to several plots inside one graph?

One of my math functions/formulas is too long, and it overflows into the next page. How do I make this one line formula into a two line formula, without breaking it up mathematically.

There is a lot of algorithm of sorting. See please https://en.wikipedia.org/wiki/Sorting_algorithm What name has this Mathcad algorithm? See please the Mathcad-sheet in attach and animation below  

I am looking for a way to create a points file using a function that I can bring into a solid modeler that can be used to create a cam surface. As a simple example, for a circle, I would want an angle in the first column, an x coordinate R*sin(Theta) in the second column and a y coordinate R*cos(Theta) in the second column. I may want to add a fourth column with a function for the profile in the z direction. Thanks, Karl.

Hello All, I am trying to calculate the Fermi integral of the order of 1/2 and its derivative. In the attached worksheet, the integral cannot be evaluated for x>0. I used an approximated model as is given in the following article but the result is not similar to what the article obtained. Koroleva, Olga & V Mazhukin, A & Mazhukin, Vladimir & Breslavskiy, Pavel. (2016). APPROXIMATION OF FERMI-DIRAC INTEGRALS OF DIFFERENT ORDERS USED TO DETERMINE THE THERMAL PROPERTIES OF METALS AND SEMICONDUCTORS. MATHEMATICA MONTISNIGRI. 36. 37-53.     Could you please help me with this problem.  Thank you very much in advance. Payman

Building a new Dell 7720 laptop to run everything from Mold Analysis, MathCAD, Bunkspeed, Keyshot etc. Already getting the NVidia M5000M GPU.   1. With Creo 4 starting to support multithreading is it now finally faster to go with Xeon? 2. Since I'll be turning off the onboard GPU that isn't a deciding factor for a CPU 3. Which do you guys recommend?? Leaning toward the E3-1535M V6 for the fastest clock.   Thanks!!!

Hi, Herewith, I have attached the problem (mcdx file) that I am having trouble with. I have a vector C with 105 elements in itI have another function x(y) with 'y' varying from 0 to 1 with a stepsize of 0.001 (Vector with 1000 elements in it) I want to find out which value of 'y' would give the resulting value of 'x' which matches the element in C. Therefore, I need to create a matrix M3 (105 Elements) with 'y' that was found out before for that particular value of C and x. For example The first element in C is 0.184. The y value 0.635  results in x = 0.184, matching C. So the first element of my M3 matrix is 0.635.Please refer to the attached MATHCAD file for the problem. Thank You!

There is one animal - овцебык (Russian) or der Schafsochse (Grrman). I think we can create and use  in Mathcad one new unit kg-cm (kg-m, m-s, s-kg etc). See please the picture and the Mathcad 15 sheet (the method of least squares😞  

Every time I try to embed a excel sheet I get  An Unhandled exception occurred on the dispatcher thread. See C:\Programdata\PTC\Mathcad Prime\Logs\Mathcad Prime_Exception_20151021_135622.log for more information. Prime will attempt to save any modified files and close. Please restart the application." Saw this mentioned for practically every version of Prime here, but no solution ?? Windows 10, Office 2016

Why is everything underlined? I checked tools/Preferences/Warnings.....nothing is on

Stumbled across this function in Mathcad 11, don't know if it exists in other versions:Symbolically it does:Does anybody have any idea what the matrix should contain?Especially intriguing is the fact that it should be a matrix of either 3, 6 or 7 rows. Luc

I would like to have in my bath room new floor - with Math & Mathcad Idea. One variant. Do you know more fine and/or interesting?     See too

Hi everybody, I am trying to use minerr for optimization of my function which has 13 parameters. The problem is that although my function and my data are sinusoidal, the Weibull fit gives me a line instead of a sinusoidal curve passing through the points. I wonder if somebody could take a look at it. Many thanks in advance.

Hello   I have 42 x and y variables where an regression are made. Now i need make an reverse function of this. How and can some help + explain how it is done so i can make it by myself in the future !!!    Thanks Regards.

Hi, I have vector and I need to check each element with a condition and the resulting answer should be a vector with the corresponding values if condition is true or false. Problem: I have a vector called M' with 100 elements in it. I want to check the condition "If (M'<1)". If the condition is true it should assign a new vector Me with M' value in the corresponding position, If the condition is false it should assign 1 to the new vector Me for the corresponding position. I am getting an error stating that the value must be scalar. I have attached a picture for your reference

I am having a problem obtaining consistent symbolic evaluation.   Toy example in Prime 4.0 worksheet is attached.   Result seems dependent upon both order of multiplicative arguments to sin function and order of symbolic key words.   Not sure what I am missing?   Physical Mathematics      

Just yesterday, my Mathcad Prime 3.1 (free version) started acting up.  When I double click the icon or run from the start menu (Windows 8.1 shell mode) I see the "splash" logo for Prime but then it disappears and a main window never shows up. Also, nothing shows up in the taskbar.  If I go to the Task Manager, I see the program, even multipe copies if I keep double clicking the icon but no window and no icon in the taskbar.Has anyone seen this before?

Dear all,   I have a (example) table like this:       |  1  |   2  |  3  |  4 -------------------------- 5  |  11| 12 | 13 | 14 6  |  21| 22 | 23 | 24   Where the top row is A (values 1 to 4), the left column (values 5 and 6) is B and the field values (11 to 24) are Y. Now I want to find the value Y belonging to A=2,5 and B=5,5 using linear interpolation. Currently I have split the table into multiple small tables, one for each column, and then first create a new table for A=2,5 and then interpolate in that table to find the result for B=5,5. This however takes a lot if programming to create the table for A=2,5 (as we have to first indicate which two tables to use based on the value of A). Is there a direct way of doing this?   Thanks in advance for your replies.  

Hi,So firstly sorry I’m not at home so don’t have an example to show but what I’m after is integrating an area and performing multiple tasks between two limiting functions.I.e I have a function which I’m going to integrate underneath. this function is in terms of x. (A line that increases up the y axis as x increases)Then I want to introduce two functions in terms of y ie vertical lines.I then want to integrate the area under the first line and between the second two. Any idea how I do this? FYI I use prime 3CheersA

Dear all,   in a design code a log-log graph is given from wich a value must be read using the known value of X. Now I have two issues:  - how to convert this drawn graph into something mathcad can work with? Getting values from a log-log graph by hand is inaccurate, so I want to use as little hand-picked values as possible to get mathcad to work with. My idea is to make a table of X and Y values and let mathcad determine a formula for this and plot this in a graph to see if it looks like/fits the graph in the design code. But how to do this?  - Secondly mathcad needs to use this info/graph to determine the value of Y from this graph. How can this best be done?   Thanks in advance for your reply.

Hi   I'm trying to make settlement evaluations below a group of point loads.   For this evaluation, I need to form a depth matrix with n-columns (number of calculation points) and m-rows (number of calculation depths), with the value of depth in each matrix element. In this matrix the depth should increase with by step length to each following row.   My try is as attached, but I didn't get this work.   Thank you for help in advance.

Hi everybody,   my question is about, how can I programming a loop for a list of values in a 3d function. I'll try to explain myself. I have a 3d surface equation and it works fine with a single values like this: but I want to repeat the calculation in a loop for a pair of list of values, something like this: What I'm doing wrong?. Mathcad reports "This variable is undefined. Check that the label is set correctly". Any idea? Thanks and congratulations.   Note: equations was obtained from thread "T-stub method" in this forum. Thanks unknown member.
