Hello,
I need some help with a solver block. I have attached the .mcdx fill. I'm trying to solve for 3 variable with 4 equations (constraints) which are a function of theta.
I feel I'm going about this wrong.
Any help is greatly appreciated,
Ken

Question regarding READPRN
I am able to successfully import data via a text file (.txt) by using this READPRN command. However when the .txt file changes (i.e. data change), the import matrix in MathCAD is not automatically updated. I need to close the program down and re-open to have the updated numbers.
The question here is, whether if there is a nicer way to do this? Another command maybe?
I know I can always do right click “disable evaluation” and “enable evaluation”, but the problem is I open/use this Mathcad sheet through an easy batch code for an another program, so mouse commands are not an option for me.
Thanks in advance!

How to add two graph in Mathcad
Hi, I am trying to model solar cell characteristics in partial shading. i need to add two graphs which i have already plotted in Mathcad.Please suggest me any general method. Further how to add independent variable? I have thought of this way once but not possible.can two independent variable ( for example I have f(x1) and f(x2)) be added to form a third variable. (I mean is it possible to define f( x1+x2). I tried the same in mathcad but it seem impossible. if this two functions are already plotted how to get the superimposed graph of two? Thanking you in advance Have a nice weekend

Reduced row-echelon form matrix
Good morning,
I am using the "erl" function to get the reduced row-echelon form of a mxn matrix. However, the results in MathCad 15 shows some fractions. If you make some han calculations you can get the unit form matrix (only 1/0 in the upper left portion of matrix) and thats the result that you get from other software like Maple, MatLab or making all reduction steps by hand. I am wondering if there is any way to get this from MathCad.
Regards,
Oscar J.

how to transfer Mathcad license from one PC to another?
Hi,
I am running Mathcad 15 student edition on a Windows XP PC. I will be selling this PC in Canada, moving to England, buying a new PC which will run Windows 7 and installing Mathcad on the new PC. What are the steps I need to take to transfer the Mathcad license?
Thanks

Launch separate instance of mathcad
I would like to make mathcad launch a separate instance of the program when I double-click on a mathcad file icon. This occurs on my machine at work but not at home. Can anybody tell me how to force this as default.

x with an over dot
There are a manner to put a dot over a variable? This is, the Newton notation, or something that else.
Thanks a lot.

Initial Conditions tracking with ODEsolve
I'm new to Mathcad and I'm having issues with the Odesolve function. It indicates that I have too few initial conditions. The error itself is self-explanatory, but my system of equations is very large and I can't find the function it's not seeing an initial condition for. This is part of a Solve block so "trace error" won't work. Is there any way find out where the error is occuring (what function) without manually going through each one again?
Thanks for any help and I apologize if this ends up in the wrong forum area.

How to change GUI Language interface
I applied on the english website, but the software is now in german, as my OS is in German. I prefer Mathematical software in English. How can I change the language of the GUI of Mathcad?
Thanks in Advance.

MathCAD Prime 1.0 is a step back
Hi friends,
well I just must realize, that Prime is a step backward. One the one hand important functions are missing and on the other hand all the experts out in the communities who has Mathcad 14/15 can not work with the MathCad Prime worksheets as it is not backward compatibility.
I think PTC must improve PRIME quite a lot, as now the userbility is other but not better. Where is the useful collabsable region feature in Prime?
comments are welcome.

mathcad 3.0 - how do I get it?
Hello,
I've been using a 30 day trial version of Mathcad 3.1 at school. After this trial version expired I bought a license code from our teacher. He bought a bunch of licences wholesale I guess back when 3.0 was still the bomb. The code I got consists of 14 positions, then 2 blocks of 4 positions. So it looks like this: xxxxxxxxxxxxxx-xxxx-xxxx
I can't figure out where to download the older version 3.0. Could I use the above code for 3.1 as well?
Thanks

Windows7 64bit and Mathcad14
Hello to all who goes in front
I have not managed to get my M14 to run ;>(
I upgraded my workstation and have done all wich have been available, but still no go.
"Unable to create 12.0 engine factory" is only indicator of the problem before 14 start-up logo vanishes.
How is it PTC ? When can I get a working release ?

Error M14
Hi,
I just encounterd multiple crashes yesterday - especially plotting with huge floating point numbers seems to stall. Storing the 8MB big file takles quite some time may be it computes all the sheet before saving.
Today I'm confronted with frequent "invalid pointer" messagers in German "ungültiger zeiger" .
2 Questions:
- what does this pop-up want to say to me?
- should I invest 320€ to head to M15?
May be also cleaning the xmcd may help?
thanks

Unable to create 12.0 engine factory' error
Hello, I am troubleshooting an installation of Mathcad 13.1. When launching from the machine with the installation there are no problems. However, This machine is on a network and the goal is to allow user client machines to launch the application served by the machine with the installed version of Mathcad 13.1. When a client machine tries to launch Mathcad from the mapped network drive the error "Unable to create 12.0 factory" is displayed. Has anyone any experience running Mathcad locally on a client machined from a server with this error? Any insight would be greatly appreciated.
Thanks in advance!

Symbolic Evaluation Variable Assignment Problem
Hi all,
I was seeing some strange inconsistencies between sheets when attempting to evaluate expressions symbolically. After some time I traced the inconsistency back to the "point" shown in the attached sheet.
The attached sheet shows what I expect to see. After evaluating a function and assigning the result to a variable, the symbolic evaluation shows the result.
However, in a different worksheet, I see the following:
For some reason, Mathcad is presenting the result as the original function. I'll post the problem sheet if necessary, but as you can see here, Mathcad has already found a numeric solution and assigned it to a variable, and has even managed to display it when called up again. But when I use the symbolic evaluation on it, it brings up the whole function. But in the attached worksheet, it does not.
Any ideas why this happens? Or at least, why the difference between worksheets?
Any advice is greatly appreciated.

Grid-lines in pdf printouts
When printing your Mathcad files to pdfs it seems to save the gridlines as a picture behind the text. This can easily double the size of your files (see annex: pdf with excel-component (also a picture) created with adobe PDF). It is therefore wise to save pdfs with the gridlines deactivated.
