Mathcad

All, I recently bought MathCAD 10.00 Prime Student Edition and was unaware that once I logged into a certain machine with the license that it would lock in with that specific machine and I would be unable to log in on any other machine. I initially synced up a machine that I do not have consistent access to and I would like to move, or reset, or whatever needs to be done, to have the license that I purchased be activated/synced with the specific machine that I want. Was wondering if anyone could help. Best, - VG

Just one question about ( min function) why it works only with scalars ... whenever I want to use it with vectors or matrics  it doesn't work ... How to overcome this ? Should I always use programming ? For example the following program : in each (qc;gem;cor ) I have 3 matrics each one has ten values.... what I need is to write a program that will compare the both variables and choose the minimum value of each one ( compare the first raw with the first raw  and chooses the min ...and so on  ) ...and the result should be also one matric with ten values. However, it chooses only the minimum value of each matrics  

My students and I use Mathcad to solve problems of dynamics. My students this year (prime 10.0.0.0) come sometimes across an unknown error when using a solve block. The error mentions "bad solve block"; refer also to the screenshot. I have never come across it before and I have no clue what the reason could be for this error. After retyping the equtions and the "find" command, the solve block executes correctly. But I don't see a difference between the original solve block and the one after retyping it. So it stays a mistery why one time it executes and the other time it doesn't. 

Hello I am working on my bachelors project. I have made a function that calculate the heat recovery in a heat exchanger with a faze change (condensation). The function calculates the potential heat recovery based on the temperature that comes out of the heat exchangers hot side. The function works fine but i can not get it to solve the function, so i can calculate the temperature based on the heat energy. Does anyone know how to solve this or the reason for the error?  

I wrote a program to correct the value of q. I wanted to choose always the minimum value and I put the maximum limit to be 15 MPa , I don't know why it is not working . Do you know how to solve this problem?Thanks  

I have  R which contains 27 matrics all of them have the same corresponnding depth ( ztips). I want to draw all of the matrics in one plot instead of having 27 plots. I tried the one Mr. Werner suggested before. However, it doesn't work here. I guess the mistake is that ztips and R are different types. The sheet is too long and I can't just substract R because it is the final result of all the above calculation. Sorry for this trouble Page 27 Prime 9 

HiIn Prime 10, is it possible to impose a domain of definition of variables?in a geometric calculation, I do not have enough constraints, and it is difficult to have a unique solution. Is it possible to specify the domain of definition of the variables in order to converge ?Thanks

When trying to add product code to a new machine i am told i have reached max license. I found Link to open a ticket. When i try to open a case i get nothing after entering the product code I purchased the code from my commerce any help would be great. or a direct phone number Thanks

Last time we wrote this function to classify soil layers. I need to show that in the plot can that be possible in mathcad ?. I need to connect the table with the plot . so it draws horizontal marker whenever the layer changes. or change colors ..any kind of change to make it possible for the reader to understand it changes layer typeLike (y ) will be both z and ztop to draw the plot . z is the depth ztop the thickness of the layers  

Although I'm using different variables, I don't know why I'm having the same results for Mi ..  It is on page 14  Thanks in advance   

Anybody know why I can't click next and finish licensing MathCad, Same thing is happening on my computer at work and at home.

Hi, It is easy using the csort(M,n) command but it only operates on one column. Is there an easy way to sort on first two columns. Also need to add if first two columns are identical ? Thanks

When running a Mathcad file in PRIME10 created in PRIME 9, I get an error:“This function accepts at most 18 arguments but is applied to 19”This restriction was not present in Mathcad 15 and earlier versions of PRIME. How to solve this? added: Thanks for your reactions. The problem can be solved with future developments.However, what about the existing MC sheets with locked areas with passwords where changes are not possible? This means these worksheets are unusable . Without an update from the author/owner of the sheet, this remains a serious problem. I would call it a bug, and Mathcad users should be warned about this problem before updating. In my opinion, the limit should be changed in a service pack P10.

Hi,I am trying to model a capacitor based of the input values for L and R and plot the results.If I plotting unit-less then the calculation is OK, others I get wired values for Xc and Xl.Can somebody can point me where is the problem?

Is it possible to import data from .dll file type and then exporting the results to .dll. ?We are planing to have a library that multiple programs can use simultaneously and DLL is our best choice. 

Hi Is there a video that shows this in action?   I found this MACAW | Page 4 | Food4Rhino  but no sound.

Hi,Why is it not found also this solution by the root function?  

While porting and revamping my set (uniqueness) functions to Mathcad Prime 10 from Mathcad 15, I felt the need for speed.  Whilst I have set functions that will handle functions (to some degree), I wanted to use a uniqueness algorithm that relied on presorting an array.    However, Mathcad's built-in sort function won't sort functions.  After having a slight think about the problem, I wondered if I could use the format string function.  I can, sort of, in some cases, but not in general.     Apart from possibly digging around in the worksheet API, does anybody know of a more reliable method of converting a function name to its equivalent string or how to sort on functions?   Stuart

I don't know why I getting this kind of result.. I tried everything. It is on page 15 . I use prime 9Thanks in advance for your help

While looking in Mathcad Prime 10 at a worksheet whose ORIGIN = 1, I noticed that with Show Indices turned on, a nested array's indices ran from 0 to rows()-1.   I tried to recreate the effect in a blank worksheet, but to no avail ... until I changed ORIGIN without recalculating the evaluated variable.  I initially set ORIGIN = 3, then changed it to 10.     Pressing F5 caused the indices to reflect the change in ORIGIN.     Equally interesting, I saved the worksheet after changing the ORIGIN definition back to 3 (with the indices showing 10..23) and reopened it.  This time, the indices ranged from 0 to 14.   On the subject of Show Indices, I would find it helpful to show an array's indices with this setting turned on regardless of the size of the array.  I've found myself on several occasions counting down an array's rows or across its columns when, say, checking the index of an anomalous result.   Stuart

Are there plans for Mathcad Prime to include automatic paragraph, equation and figure numbering?   It's not ideal, but MP10's Advanced Controls allow a rudimentary form of entity numbering.      The topic has been broached several times since at least Mathcad 11.   https://community.ptc.com/t5/Mathcad/Mathcad-and-articles-for-Journals/m-p/442066   Stuart

This sheet first plots a series of x,y,z data points for a floor elevation survey. surface is plotted as raw data Then it does a surface regression analysis and generates a polynomial the poly surface is plotted. I need to determine the curvature and then radius of curvature for any and all points.  I will use an overlay of distress to determine the radius of curvature that causes distress, I currently have a slice method of raw date and of the surface  but this is cumbersome.  A math prof colleague provided a solution  that runs OK on his old version  of Maple.I'm attempting to get this solution using MCAD 15 but getting errors.  I think it may be  a simple deal but don't know.  Can anyone help? I've placed a number of markers in this sheet in Bold large font red text..  Solution  starts on page 9.  There's  hand written solution  at top right of page 1 and repeated lower. BTW this is a

I would like to go through the same worksheet several times, changing "index" and the various parameters, and put the calculation results in the same Rez matrix, in the corresponding "index" column. Unfortunately the previously defined columns are set to zero.

I'm currently running PTC Mathcad 9.0,0 on Windows 11 Pro.  After renewing my license, I received an email with two license files. One of the text license files has the word "standard" at the end of the file name. which do I use?   I've opened each in a text editor.   I do see at least one difference.  I see the word "BORROW" in one of the licenses.    Any idea why I would receive two licenses?  What are each for? 

Warm greetings to all,I remember that a few years ago, a post was published asking how to write one or more points overlapping the function to be derived, instead of one or more apexes, but I can't find it, so how can I do it especially for MATHCAD 15? the difficulty lies in placing the dots on the functions, then we proceed with the prefix operators and the like. Thank you very much.
