Mathcad

Hello! Is it possible to do the following:I have two matrices, say 5x1, but want to perform computation using 4 elements of both matrices. In other words I want to omit one row (value) form the computation. The result will be vectorized.  Best regards,Sergey

I want to make use of the 30 days trial. After installation the license wizard requires the product code. Where can I find that?

Hello!. Please, help with the following issue: I have defined two matrices and use them in equation where they are being multiplied. By some reason I get only one value instead of an array. If I define the one matrix ("k") as a variable, then the computation goes on, as it should, and I get an array. What I am doing wrong? 

I have a copy of Mathcad 14 (with the original disk and receipts).  My computer died and I had to move it to a new computer.  During the install, it goes to log into PTC to get the license (after entering the product code), but returns errors saying I don't have permission.  I've got the license file from the old computer, but since it is tied to that computer, it doesn't work on the new one.  I've gotten no response from PTC when asking for help. FWIW, it's on a brand new Win 11 computer.

It would be very useful if Mathcad supported a column-based or region-based document layout for engineering calculation sheets. In traditional calcpads or formal calculation reports, calculations are often arranged into clear vertical sections, for example: "Reference / Code clauses / Assumptions""Calculations""Results / Output"At the moment, Mathcad provides a single continuous canvas with free placement of text and math regions. While the grid helps with alignment, there is no way to define fixed columns, regions, or containers that keep content aligned consistently. A typical example:On one horizontal “row”:Left: a short text description (e.g. Bending stress)Middle: the actual formula and calculationRight: the applicable code referenceCurrently this requires manually placing and adjusting multiple text and math regions, which becomes difficult to maintain and easily breaks when edits are made. It would be beneficial to have something like this implemented as it&n

Hi, I created a file in Mathcad Prime 8.0 and I'm sharing with my client who is using Mathcad Prime 7.0. But he's unable to open due to compatibility.Can anyone help me out please on how to create a file that can be opened in Mathcad Prime 7.0 as well.  

I have been using Mathcad 14 for many years. After upgrading to a new PC, I tried to reinstall Mathcad 14, but the licensing process failed. The website returned the following message:The remote server returned an error: 403 Forbidden.Could you please assist me in resolving this issue?

Trying to transfer license from 1 system to another.. Webpage when trying to get license, etc said i don't have enough permissions / access denied. So i can't manage my own license i payed for.

i wanted to install Mathcad 15

Hi everyone, I'd like to ask whether it is possible to hide the display of the z-expression/z-axis in a 3D plot? I have attached a picture and marked the area in green to show what exactly I want to hide. Thanks for your thoughts!Uwe

Given how little versions changed, it has frustrated us all that we cannot save in older versions.  I suspect this is largely a marketing ploy to force upgrades and new purchases. And, probably controlled by a simple version check.  So after a little thinking, digging and experimenting, I have been able to open 5.0 files in 4.0.  I haven't played with it much and I'm sure it's limited - but it might help someone someday.    With the new version file a.) Change the extension to .zip b.) Unzip to a folder c.) Delete app.xml in docProps folder   With the older version i.) Save any file ii.) Change the extension to .zip iii.) Unzip to a folder iv.) Copy the app.xlm in the docProps folder v.) Paste this 'old' app.xlm into the folder where you deleted the last one.  You should just be able to re-use this file anytime you want to do this.   Go back to the 'new' version folder: Re-Zip all folders and files that had been unzipped. Change extension from .z

Topic reference from hereSame problem here. I purchased a license for Mathcad 11 Prime Student Edition, upgraded my account, but the download page says that I am not entitled to download software. As I purchased a license, I request immediate access to download. With the license came an activation code, but without the software I am unable to activate. 

Hi there, I just bought the student license for Mathcad Prime but when i go to the installation pag,e there comes up a problem like i dont have any available product. I put in the activation code from the mail I got from PTC/Clevebridge but nothing happens. Any Ideas ? Thanks,

Hi, Is it possible to reset variables? For example, if I want to have one file with multiple different calculations inclduing a variable for diameter, is it possible to have a line break or something, so that any variables above it are not used? Therefore variable for diameter needs to be redefined again.  I know that just re-using the same variable redefines it, and that I could use D, D_1, D_2 and so on, but I do not find these acceptable solutions as it increases potential for calculating errors. And sorry for asking this, I know this must be a common question, but I don't seem to be finding the old ones.  

Please provide me acces for educational purpose. Thank you.

I am trying to find a Variable in a "F"+subscript(tl) format. Find only searches for "F" alone, but that finds F with any subscript or tl but that finds any variable with tl subscript. How do I find my "F"+subscript(tl)s? p.s. This forum wont even let me format the subscript ...  p.s. If PTC decided to wage war upon subscripts, why did they not superscript them in the convertor???

Hi - I have an old version 14 of math cad and I would like an license file for this. It is an upgrade from version 12Can you help me. Thanks Erik

Dear PTC Mathcad Community,I want to ask for clarification on the behaviour of units and symbolic substitution in Mathcad Prime (similar topics have already been raised, but I still haven't found an appropriate answer for my issue). So I try to find a symbolic expression for epsilon_c2, which is a parameter of the equation N.Solver succeeded with the issue, but with incompatible units (see picture)So, I have tried to find out the solution in the community, but the advice of @Werner_E  with calculation options didn't resolve the issue (see the picture)So my issues are: 1. How to make the symbolic solving more "seamless" with appropriate units' manipulation in the solutions?2. Why does Mathcad not see the assigned values of the  epsilon_c2 obtained in the previous solution? After some time, when the file has been refreshed, some magic happened, and now I can use the roots of epsilon c1 and c2 in a "normal" manner.But the next issue is that it doesn't let me

I am trying to upgrade my PTC account so that I can download MathCAD, but am receiving an internal error message when I submit the upgrade request with my customer number and site number or sales order number.

I have two vectors .. ztop and z ztop shows the depth of each layer (cumulative value of z in each layer) . ztop  has 11 valuesz shows points in that depth .. it approximately increases by 0.02 in each layer. ( it has 3670 values) each layer has its gamma and its ztop .. ( both have 11 values)what I need is to write a program that will repeat gamma values for each z so I get the 3670 gamma values . In the first layer instead of having one gamma( 17 kN/m3) one value for all the layer , I need to get a vector which repeat this gamma as many as z in this particular layer .. and do the same for the rest layers. Can you help me with that? 

Recently, I was in the position of trying to explain to a 6- and 8- year old how to play the board game Battleship. (Kids from my generation had commercials that seemed to explain the basics of the game fairly well.) While trying to explain the concept of the grid to them and search algorithms, I couldn’t help but wonder, “How could this be done in Mathcad Prime?”     This month’s challenge, should you choose to accept it, is fairly open-ended: simulate various aspects of the Battleship game in Mathcad. Here are some suggestions:   Write a program that will place the ships on the ocean grid. The ships must be placed horizontally or vertically; no diagonals. Ships can’t overlap one another. Do you place the ships randomly or according to some kind of optimized algorithm? Alternatively, can you use Advanced Input Controls to allow the user to place the ships on the ocean grid? Display the placement of the ships using the plotting capability. Write an algorithm for

I want to use Python scripting in MathCAD Prime 11, but upon selecting python in the dropdown menu in the advanced controls editor, MathCAD hard crashes. I don't even get a chance to press "apply" or close the dialogue box. Everything closes. There is no stalling or freezing. It just crashes instantly. No error message is produced. What is going on? How do I fix this? My understanding is that, if Python shows up as an option, MathCAD has registered to appropriate location for the python executable. Is that correct? Python version 3.9.18 Steps. 1. Start MathCad with blank worksheet.2. Insert Advanced Control "Text Box"3. Name variable "aaa0" (or anything really).4. Right-click on the text box and press "edit"5. In scripting language drop-down box, select Python6. Watch MCP 11 crash.

I've saved the file on Mathcad Prime yesterday and today it's unable to be open. Unfortunately no restore file has been saved. Are you able to help with restoring the file?

Hi,I have a problem that is sensitive to guess values. I am attempting to copy a method that was posted some time ago https://community.ptc.com/t5/Mathcad/Solve-block-problem-3-1/td-p/43434 but I get an error as follows:I am sure the fix is trival but I have a had no luck fixing it. Any help would be appreciated.ThanksRoss 

Hi everyone, I have this function that I used to find R from it  Now I want to find the min, max and max  from it ..but didn't work . It tells me that the values should be scalar  and when I do this , it gives me the same results of the original one not the averageI need to find the min, average , and max valuesThanks Yusra
