Mathcad

Hello, I am using Mathcad Prime 10.0.0.0.  On sheet 3 I am trying to call in column 2 (via data[i,2] in the first IF statement) which has a text name for the value.  If the value equates to something in my IF statements, I want my program to calculate the H_f or Friction Head.  I want the program to go down the array one at a time and at the end output the sum of all the individual friction heads added together, so I gave the array the indices of i,2 with i going from 0 (first value in the submatrix 'data') to p-1 (end of the rows in the main Matrix 'System').  I am not sure why I am receiving an error which states "This array index is invalid.  The index must be an integer, not less than origin, and not greater than the last element.".  Is there any chance you all may be able to assist?  Can a variable not be in the Array index?  If not, how do I go down my list?  Should I have individual vectors (single column arrays) for each co

Could someone please help me with what I am doing wrong here?

I am trying to use runif function however whatever I am plotting it looks the same. I am using ver 9.0

I have used Mathcad Prime 10.0.1.0 for one month and I would like to purchase the full software for one year. I am a student at University of Wisconsin and would like to purchase the student version. When I select to buy and provide my info, I get a dialog that says to watch my email for a link. That email never comes. Can you help me purchase the student version? Thank you - Dave

I have converted the template from 15 to 10 and now i am trying to use the reference file but the there is error as attached. But i could not find any error in the reference file. In reference file i am reading the data from excel. But no errors here. 

Could you please assist me with integrating the attached function in Mathcad? It represents the probability density function (pdf) of the Gamma distribution. I know that the integral should evaluate to 1, but I am unsure how to perform the integration in Mathcad without specifying the values for alpha and beta. When I assign specific values to these parameters, the integral correctly evaluates to 1, but I would like to achieve this result symbolically.Your guidance on how to proceed would be greatly appreciated.

Hi, I would like to change PTC mathcad langage without re-install in order to have the right translation of french error notification.Do you know how to do that ? Thanks PTCmathcad 9.0

I try to convert mathcad 15 Taylor serie to PTC mathcad 9.0.It seems that mathcad 15 could treat Taylor series with several variables but not PTC mathcad 9.0.After PTC conversions, PTCmathacd 9.0 give the following error : more than one independant variableCould you help me to solve this problem ? Thanks

I have a default set of units that are included in my document template. They are there because I use them regularly.  Having a bit of fun, I have attached a sheet with these and about 50 more.  Who doesn't compare area to Rhode Island or volume to a cord of firewood? Feel free to add more.Bob

Following up on thr thread https://community.ptc.com/t5/Mathcad/LeastSquaresFit-usage-for-Foster-Model-parameters/td-p/100070  Why does genfit blow up when provided with the actual Foster Model thermal fitting function and guess values used within that model when fitting to @VD_12953418 digitized plot data?  I would have guessed that the genfit result would have been close to the plot of the model or to the example of digitized data.

Good day, I am a newly hired teacher at the HTL Rankweil. From there I got a user license for MathCad. I may have made two mistakes when activating the license. I had downloaded version 10.0.1.0. But my colleagues all use version 10.0.0.0. The license I was using may only be valid for 10.0.0.0 and not 10.0.1.0. That's why it stopped working the next day.   Or it was because I used my private email address when registering for the account and not the one that belongs to my school.   Today I wanted to activate version 10.0.0.0 with my school email address. Unfortunately it was not possible to open an account. The system reports back that there is already an account.   That's why I would like to ask you to delete the account based on the private email address.   Thank you Torsten Soetbeer     Translated by the Community Moderation using Google Translate.    Guten Tag,ich bin neu eingestellter Lehrer an der HTL Rankweil.

My Mathcad application doesn't start, i tried to reinstall it but with no succes. It only shows that the application is in the taskbar, when i press on it a small window above the taskbar comes up and it is black. I urgently need your help for a project that i am working on for university. Thank you!

I have to use Mathcad prime for my engineering course and since it I cannot purchase it right now I have been using the 30 day trial. So once I started the 30 days I thought it would be fine for 30 days, but for whatever reason the trial period disappears after a couple days or a couple hours, putting me back in mathcad express. My work-around for a couple days was to reacquire the license through the licensing wizard. None of my friends have had this issue, and I have now 'run out of free trials' even though I would be halfway through my actual 30 day free trial.

So, I've been able to work through all the values so far but seems like I have a problem with the summation notation since the THD of alpha does not converge to a solution:     

hi ptc team,i use PTC Mathcad Prime 9.0.0.0 convert xmcd file to mcdx, but there are so many errors in mcdx file,how to resolve? please help.

I encountered an interesting and maybe concerning problem in how MathCad solves its intergrals between different versions. In the version of MathCad I use (MathCad Prime 9.0.0.0.) the integral I wanted to solve and get an analytical expression to gave one answer. This answer is different from the answer you get on older MathCad versions. I noticed this from some old reports where this integral was solved via MathCad about 20 years ago and they get a different analytical expression. This expression you get from the older versions is also the same you get by solving the integral completely analytically (which you can do via variable substitution). The difference between the answers seem to be very little and the residual could just be some numerical truncation maybe, but as we can see the difference is not completely negligible depending on what you are after. Has anyone encountered something similar to this and know why this is the case? 

I'm trying to find the product code for Mathcad prime. How do I find this?

Is it possible to export out a scalable vector file from Mathcad prime worksheet? If yes how can I do that? 

How do you have the plus sign "+" be a subscript? Every time I try to subscript the plus sign, it just becomes an operator. But I want it to be part of the subscript.

Hello all, I'm trying to do a fit for the transient thermal impedance of a transistor based on a set of points that I extracted from a datasheet. At first, I tried to do a simple polyfit, but it seems that the fit can diverge to very high numbers or even go negative, which may not be acceptable in this case, since the thermal impedance is strictly positive.I tried to do a fit similar to the Foster thermal model, based on R and C couples of values, that is usually used in the thermal models of electronic components. For that, I tried to use the LeastSquaresFit function, but it doesn't converge in my case, script attached below. Could anyone explain the reason for the divergence ? Is it the input data or the way it is used ?In the case I try to separate R and C values to 2 vectors, should the guess vector be the stack of the R and C vectors ? The documentation of the function doesn't explain it in a clear way.Alternatively, in the case of a logarithmic regression, is it po

How do I get Mathcad to get from this:to this:without having to redefine f(x) myself?

Hi,Which software do you recommend for verifying bending moments and shear forces in a beam from Mathcad calculation?I use the beam calculator https://solveredu.com/en/beam-calculator/. It's generally good, but do you have any other recommendations?
