Mathcad

Dear All, I hope you are doing well. I am new to MathCAD and am trying to solve simultaneous equations using the least-squares method, however, every time I input the equations the variable is not recognised, even when I state the values one by one.  I am attaching my work. If you help me it would be much appreciated.  

I went here  Code ExamplesThen HereMathcad Prime API Example: Microsoft Visual Studio C++ ATL | PTC  Then I got:Is it just my PC or is the link dead?

I do not have a product code for the students version

Good morning I'm hoping that someone may be able to help me with a monte carlo simulation problem. The function I wish to use has a root within it, which gives me an error. As soon as I remove the root from the function and use the rest of the equation, as my function it works, but obviously giving incorrect results. Ive attached the baisc problem, if anyone can helpThanksRichie

I installed Mathcad prime 8 to use on a free trial. I try to open it, and the plash screen comes out with the logo, but it stays like that and the program doesnt actually open. Also the same happens to the prime 7 version

Hello PTC fam, it seems the Find function doesn't work at my end. Mind to take a look? I attached my file  

I am having issues in using the product code to upgrade from Mathcad Express to Prime 8. The Product Code begins with MX

Hi everyone,I've been using Mathcad for a few years already. However, I just discovered its API. I did a few google searches and couldn't find a documentation for the API or any resources other than this forum. I'm just wondering if you guys can help me point to some places? (VBA/Python) Thank you very much!

I would like to use API to change/define variables values(string and fraction) that occur at the very beginning of my calculation sheet. Also, sometime I will calculate some values in the middle of my calculation sheet but might need to redefine it later in the same file.How can I do these? Could someone point me in a direction. I have just started using API for Mathcad. (VBA/Python)Thank you very much!

When I try to calculate the cross product of two three element vectors I get an error message on the first vector"This value must be a 3-element vector".  I am using Mathcad Prime 8.0.0.0. I have tried the same thing on 7.0.0.0. I have changed the vector and matrix index Origin to from 0 to 1. Jack Smith, Katy TX `

Hi everyone. Do any of you experienced structural engineers use PTC MathCAD Express (free version of MathCAD) at work? If so, would you recommend it, and why or why not?I've used it before for school, but I experienced some limitations with it (for example, the # of rows permitted in a table is limited, whereas on Excel it's not). Compared to Excel, I like how the finished calculations look so clean and polished on MathCAD, as well as how the software takes care of units. However, if Excel is more versatile and better for structural engineering work than the free version of MathCAD, then I'm sticking with Excel. Thank you in advance for your expertise!

As per this thread - same issue   Dear Collegue!I have tried these Resolution but nothing worked!I have the MathCAD 8 express free version and I can´t open the .mcdx file.Till today there weren't any Problems opening the file. The Problem is I can neither open it nor convert to pdf but need the calculations ://And I am speechless because its a very important file to me and I need it for University.I would be very thankful if somebody could help me!!! If somebody could convert it to pdf it would be enough for me.   In kind regards!

Related to this thread:   @Werner_E Hello Werner, I am currently looking for a way to process hexadecimal numbers with Prime and unfortunately I have seen that there is nothing out of the box. Now I would like to save myself the work of developing my own functions and using your preliminary work. Can you post the file here (I'm currently working with Prime 7). Thanks very much--------------------------- Hallo Werner, ich suche gerade nach einer Möglichkeit mit Prime hexadezimal-Zahlen zu verarbeiten und habe gesehen es gibt leider nichts out of the box. Nun würde ich mir gerne die Arbeit ersparen eigene Funktionen zu entwickeln und Deine Vorarbeit zu nutzen. Kannst Du die Datei hier posten (ich arbeite aktuell mit Prime 7). Vielen Dank

Friends!My book "Leo Tolstoy and Math" was published, where the examples were solved with the help of Mathcad. The book, however, is in Russian (see attachment), but you can view the illustrations. I show one of them.I am currently translating the book into English and would be very grateful if someone could help me.

Hello guys, I'm a newbie and I want to ask how to read these mcdx files with MathCad. I can't get them open in MathCad.. Any idea?     Original Post

  Hello,   I was able (with some help from the community 🙂 to solve a single ODE using a MathCAD 5.0 Solve Block but now I want to solve a system of 3 ODE's but I am getting an error (see attached file).   I suspect I am making some newbie error. If someone can enlighten me as to what that error is and tell me how to do the calculation correctly, it would be much appreciated.   TIA,   --Doug  

On the MCad15 version I used to use Combobox (Microsoft form component) linked to Excel to feed the control as database.I have noticed that Prime 7 has its own Combobox with some limited input options and does not allow import MSforms as object.Does anybody has any recommendation for this topic or it's something that could be included in new releases?Thanks in advance

This seems to be a bug.  Prime 7 won't plot degree C or F on the x-axis of a plot.  (Kelvin and Rankine work fine).  And degree C/F seem to work fine on the y-axis.  (I know degrees are technically functions and not units in mathcad, but this worked in version 4.  )  Is this a bug or a quirk?  any workaround (besides using absolute temp - which isn't very practical)     Prime 4 file attached.  open in 5-7 and refresh and you should see the error.     Thanks,

Is Mathcad compatible with Windows 11? I have tried a couple of Windows 11 PC's and can't get the install to launch. Is there something special we need to do?

How do I get Mathcad 15 trial ?Where do I find Mathcad 15_EN.zip ?

How do you create dot variables? One dot on top of the variable indicates first derivative, two dots, the second derivative. I'm using Mathcad Prime 8.0.0.0.Thanks!Jack SmithKaty, TX

Hello!Is there a way to change the inline division sign from this "÷" to that "/" ?I saw arguments about the slash sign can be misread to 1, but as is the division sign can be misread to +.It would be great to be able to change the operator styles as we please.Or can I find the files where the operator characters are stored, so I could override them manually?P.m. Im using Prime version. The goal is to be able to see the following: x/y, and not x÷y.
