I used the READEXCEL command to create a matrix that I can use Lookup Functions on.The Lookup Functions work perfectly except I can NOT compare the values as shown below:Help?

Mathcad Prime gives me 11.833 as answers but need to get and show the equivalent fraction 71/6.How can we convert from decimal to fraction?

I am very new to the image processing functions in Mathcad prime or Mathcad 15.0.  In the image processing functions, I don't know what "melem" does.  When I look in the help files, it says that "melem" is a vector or matrix.  I can get my functions to work with a basic matrix but I really don't understand its purpose or function.  Does anyone else know?Thanks ahead of time.

Hello;I have 5 equations 5 unknowns in the solve block which all of them are functions of a range variable. Solve block always gives error, what is wrong?Please see the attached mathcad file below. Thanks for help

Dear Valery!Perhaps it has long been known, and maybe something I do not understand, but I have encountered such a strange situation - Mathcad 15 is completely wrong working with dimensional quantities in a solving block.Example - in the attached file.Regards,The man from the image of this group.All OK in Prime

To al,How does one create a surface plot like the example attached in mcad?ThanksRegards

That's the question,     What are the best free sources to learn mathcad?Thank you all.

HiAny one can help me to simplify the summation using matrix index.My advance appreciation for the continuous support in our Math cad community user,

Dear all,I am a beginner of using Mathcad 15 and I have a very basic question regarding to the data import and solving an equation. I try to simplify my questions: I have a text file containing two columns of data with column 1 is "a" and column 2 is "b". I would like to solve the equation a*x^2 - b = 0 to get x value. This means once I import (a0, b0) I have x0 export and so on so forth. I would like to export all x values into a file. Can someone please tell me how I can do this? Thanks a lot in advance.Best regards,Chien-Lung

This worksheet shows the calculation of a transmission line parameters used for LW/MW and Shortwave broadcasting stations. This TL is classified as unbalanced and of the very high power type and consist of central copper tubing conductor and eight copper solid parallel wires. Using Mathcad Prime 2.0 is only to show the equations used in calculations withouit plotting or optimization.I have included an executable version of the program written in VB 6.0 with GUI and slide control to vary the line parameters. VB 6.0 is still very alive and in use up to date. The icon is also designrd by me with my initial letter "A" of my name. I hope that the readers wil enjoy it.

Basically the answer should be a perfect zero (according to theory and also verified through hand calculation), so why this software is giving such high error.Please tell me if I am doing something wrong as soon as possible.

Hi Everyone,I'm new here, so i dont know if i written this question under the right subjekt. I will start with saying that I'm sorry for my bad english.Now to my question:I'm sitting right now with a projet where i'll try to make a template to calculate some buildning structures. When i Do a bending moment controll i get an array (a vector) which has negative values and positive values in it. How do i in simple way extracting those elemetns which is less than 0 in a own array?Like if i have a Vector A: [0                                         10                                         

Comment extrapoler une courbe dans le sens décroissant.

I want to create a global result table with fixed columns. From anywhere behind the definition of that table I will insert new result lines or modify existing rows. For modification, the first column is a key column, so that the match-Function could give back the row number:My problem is, that the ResultTable will not be changed. Also not if I writeResultTable:=AddResult("key123","Cap1","that's a nice result",4.5)Yes, I know that inside a program the assignments are local. How to make global?Thank for help!

Hello all,Please, is there any way to generate a table of contents in PTC Mathcad Prime 3 ?Thanks in advancedBest RegardsRedwane

Check attached files.My attempt is to solve for x at a certain p value. Can anyone explain why the solve command and solve block fails?According to Brent Maxfield's monograph “Essential PTC Mathcad Prime 3.0 (2014)” ch.10 pg. 312, the 3.0 version has a bug with modifiers which could implement constraints. Has this been fixed in 3.1? I want to eliminate complex roots and filter real roots.. Will assume command be any use in 3.1 as it make no difference in 3.0 version?Does the solver fail because of the expression in the equation “’x’ to the power ‘i’” where x has multiple roots and “i” is also running from 1-14, 1-17? However, in reality “i” is affiliated in sigma and when expanded it cannot be considered as a range.. Can this be sorted if I re-arrange it in vector form? Like using a vector and a poly-root command?Check attached file “Patek & Klomfar..”. If you look at the last 2 equations which I’ve disabled if not it will take nearly 5 hours to solve each. (Should be done one at a

Hello Everyone,   I need to have only one specific value from the table, suppose I need only Cu=60. How can I refer a specific value from table.       Thanks

Assuming I have a simple function such that f(x,y)=x^2+x*y+y is it possible with Mathcad Prime 3 to find the symbolic partial derivative of the function f'x(x,y)? For some reason I cannot find how to do this. f' seems to only give a normal first derivative. Is there some tricky keystroke to enable partial derivative notation in MC Prime 3? I find it hard to believe that PTC would have overlooked that functionality?Kind regards, Mark

Prime Users,Does Mathcad Prime has a built-in function to find the squareroot of a matrix?I do not see one with my M14.Thanks...

Quiero trabajar con varias constantes, pero simbolicamente, ejemplo: nu(ν), rho (p), etc. Cómo debo hacer para definirlas y que el programa no me diga que no están definidas.

I am not a power user but occasionally need to plot simple vector functions such as, say, response of a system over a range variable like temperature or resistance.Can this be done with the "free for life" version that I thought I was downloading?Thanks

I was wondering if someone could please give me an example of what each input in the LeastSquaresFit() function in MATHCAD Prime 3.0 looks like.  I have been struggling particularly with the syntax of the function to fit data to. Thanks
