I don't think this is possible, but hope dies last, so hence this post:   Is it possible to plot multiple traces in Mathcad Prime with the arguments being sourced form a single matrix or array?Let's say I have a simple function of the form f(x): 2x + a I have an array of 'a' values: a: [1, 2, 3, 4, 5]   I wish to plot 5 traces (a trace for each value in 'a') without manually adding and writing out the function five times in the plot window (there will be cases when I might need to plot many more than 5 traces, so looking for efficient methods).   Your responses would be greatly appreciated.

to all math experts,   I have started looking at a method involving PSD and co-variance matrices. I am trying to set-up an example in mathcad (15) out inf interest and struggling with an eigenvalue extraction. I think I need to "invert" the problem but don't know how. Attached mcad15 file and a pdf. see sheets 4 & 5   Some pointers on my ignorance would be welcome   As a side issue: I am correct in thinking that one cannot calculate the cross-spectra  PSD form 2 PSDs   Thanks Regards

One mathematician has said me that if you have 6 parameters in the minimize function - you must have 6 or more equations in this solve block. I have only 4! Is it correct? See please one interesting problem in attach! Thanks! 

Trying to help an instructor solve a problem. He has requested that we go back to an older version of MathCad because Prime  can't do what he needs. Example provided below.   The MathCad prime cannot plot a figure (Z), when the variable (Y) is a function of another variable (x). Example: ------- x = a, b, ... c Z = f(Y) Y= f(x)   Plot Z as a function of x. -------

I am needing assistance integrating the attached equations. What I am wanting is a symbolic result of a generalized Maxwell equation for the force generated by the flux density. I have the flux density equations and the Forces (Fx,Fy) is the cross product of the Z cross Y and Z cross X components respectively. taking each independently and integrating twice will result in the the force.    What I need is the resulting symbolic equation.  my attachment only has the Fx info Fy is a similar result. What I am looking for from the community is some suggestions to how to break this down so it will integrate?      Thanks looking forward to your responses.   Richard

I can not figure out the syntax mistakes I am making. I know there is a way to use matrix callouts together with symbolic equations. In the included example I want to get a 3 row 1 column back where the top row is calculated using the top row of all the matrices mentioned and the second row is calculated using the second row of all the matrices mentioned and so on. Where am I going wrong?   Thanks

I'm modeling glucose conversion to ethanol through solving a series of ODEs of enzymatic reactions. How do I set the constraint that all concentrations are >= 0 and the total mass of all compounds in the pathway are constant over time. Any help would be greatly appreciated!

Hello,   Is there a way to export data from Mathcad to excel. My Mathcad version is prime 4.0.   Thank you,   Faisal

Hey, I am from Germany and need some help. I am new with MathCad.   I want to calculate the insections of 2 cycles.   My Problems:   The plot of 2 variables in 1 diagram doesnt work. I tried it on the x-Axis with f(x,y) and on the y axis with x,y. No cycle is shown.   Then next problem is to subtract f(x,y) - g(x,y). Whats the Syntax? Can somebody tell me?   Is it possible to write a litte programm which calculates me the intersections or tell me the solution? My program: m11:=0m12:=0r1=8 m21:=7m22:=8r2:=3.25 f(x,y):=(x-m11)^2 + (y-m12)^2 - r1^2g(x,y):=(x-m21)^2 + (y-m22)^2 - r2^2 h(x,y):=f(x,y)-g(x,y) Thank you.   Greetings MM

Help please - see the attach

Hello,   I am trying to assign the last row of a vector of values to my result. I want to start assigning from the second column and assign that value in the first column of a new variable but it is telling me that array index is invalid. Please help me to solve it.     Thank you, Faisal

Hello, We've been using MathCAD 15 for years and have many calc's made using Combo Boxes.  I recently upgraded my machine to Windows 10 and get errors when opening our programs.  We got a new computer for a new hire last year with Windows 10 and everything worked seamlessly.  I think I may have figured out the problem, but I have no idea how to solve it.  The ComboBox that we use is apparently the Microsoft Forms 2.0 ComboBox, it shows up as below on my co-workers MathCAD under the Insert Component.  However when I go to the same location the option for Microsoft Forms 2.0 ComboBox doesn't exist.  How do I load or install the Microsoft Forms 2.0 Objects?  I've searched online everywhere and can't find anything that works.   

This may seem like a silly question, but I can't figure out a simple keyboard shortcut. I searched online but to no avail. How do I select the math range that I my cursor is in?? Say I want to delete a math range. How can I do that without using the mouse. Say I want to move a math range around, how do I do that without the mouse?   This would help my flow in mathcad tremendously since I wouldn't need to pick up my mouse and make a selection box to help organize my work.   Thanks a ton for taking the time to answer my simple question!

Hello,   I have a data that contains the position of a particle as a function of time. When I apply the fourier transform I do not get any frequencies however through the time position graph and the position histogram, I can see that the particle has a position around which it oscillates. I also need to calculate the power spectral density (PSD) as a function of frequency. Has anyone ever worked with something like that? The original data is attached.   Thnak you.   Ulisses

I'd like to make a code which can make the empirical graph of dice when the dice is only "6" However, as you can see, the probability is not the same as theory.  Is there anybody telling me the mistake that I did?  The answer has to be '0.166666666...'   plz, help me  

Please help. For many years I used Mathcad 15 with embedded excel. Starting last week, when I open Mathcad file, the excel table loses all highlighted colors and borders, which were implemented in the original excel sheet. When I double click on the excel table, I can see all colors, but clicking outside the excel table makes all colors disappear. Could it be related to Microsoft office recent updates? I use excel 2010.

Good morning friends of the forum, I am new to mathcad, I would like to ask a question with the masters of the forum, how can I build the problem that I send in jpg in mathcad prime, I will post the solution of the problem that was made in microsoft mathematics. I wonder if it is possible to solve the same problem in mathcad prime. Attached also what I can calculate in mathcad, is incomplete.  

Hello,   I want to plot my values in Y-Axis such that the lowest stays in the upper and the maximum stays at the bottom without changing the sign. How can  I do it? Thank you very much.   Faisal

Hey guys,   Some of you know about my effort to reproduce an old work of my advisor, eventually, I decided to use Mathcad 15. Now, I'm having some issues in some parts of my work, apparently is with one variable called "εs" and I don't know how to solve it, I'm very new in mathcad. I'm putting in annex the work of my advisor and my file. Can anyone, in the name of everything that is sacred, help me?

Hi. I'm using Mathcad 15 and looking for a good guide or help how to plot vectors, spheres like this:

I tend to do a lot of partial differentiation in my analyses and how I currently do it is to hard code each partial to their own variable. This tends to clutter my analyses, since I deal with rather large multi-variable equations. I tried being slick today by defining a 1xn matrix (where n is the total number of variables and each element contains the variable names that I need to do partial derivatives on) and performing the partial derivatives on that matrix and vectorizing it. Mathcad doesn't flag an error, but what it's calculating isn't correct. I believe it's trying to do the differentiation on the value of the variable rather than seeing it as a variable by itself, because it always calculates the result as 0. Does anyone know how I can get mathcad to see these as variables or know I better way of going about this? I've attached an example of what I am attempting if it isn't clear in my writing. 

Hi,   I get a "No Solution is found" from the find() in this solve block in Mathcad prime.  Can someone please tell me where I'm going wrong?  (code attached)   I have noticed that if i put the initial guess in for 'h' as the answer then the solve works but this defeats the object somewhat.   Thanks in advance!
