Mathcad

Hi, I'm new to Mathcad Prime, having used 15 for a while now. I've been looking with interest at the API offered with Mathcad Prime, and I have had some luck in recreating some of the various PTC examples in MATLAB using  actxserver("MathcadPrime.Application")  to link the Mathcad COM server to MATLAB.Where I'm encountering issues is extracting values from a matrix. Using the test.mcdx file provided with the VBScript example, I can retrieve the value of output1 successfully, however I'm struggling to do the same with matrixOutput1.I'm using the following to load the matrix: prime = actxserver("MathcadPrime.Application"); %%Open a COM session for Mathcad prime.Activate; %Focus the Mathcad window (not necessary unless you want to see what happens) dir = "C:\[...]\test.mcdx"; %Path of worksheet to open ws = prime.Open(dir); %Open the worksheet and create an object to represent matrix = ws.OutputGetMatrixValue("out_0") When I query the rows

So, Prime 10 is imminent eh? The trumpeting has started and the new enhancements that are touted sound like a list of corrected bugs. Undoubtedly, there are some useful improvements but I fear that the big one is still missing. This big and very visible problem with all Prime versions to date is the very poor quality of the plots. Compared to the MC15 (of blessed memory) plots they are very primitive and limited and definitely not presentation quality. And for technical applications good plotting facilities are an absolute necessity. So, as it stands now, if you need some proper plots for, say, a presentation, then you have to export the data to Excel and try to make a plot there. For technical plots that's often not optimal and you may have to resort to a freeware or paid plotting package like Veusz or so for, say, decent polar plots. Well, that's irritating and cumbersome to say the least. To improve plotting  facilities start with a look at the MC15 plots. They had their l

In this case I want  to allocate a result of substitution to Eq1, It seems to works for the substitution but  then Eq1 seems undefined. What happens? Then it might be the reason why the 2nd substitution is endless.  However, when i try to make 2 substitution in the same execution command, it is endless too.What happens  ?  Is there a relation between those 2 cases ? Option calculation for constant unit with symobilc math is set.PTC MathCAD prime 9.0.0.0.0

I have the following simple equation And all i get is undefined....  Any ideas?  

Good evening.I am trying to use user-defined FORTRAN functions in MATHCAD PRIME 10. Unfortunately I do not have the Compaq compiler mentioned in the online help. Does anyone know if other compiler such as Intel OneAPI can be used and if the procedure is the same as described in the online help? My concern is about the libraries that MATHCAD PRIME needs that are Compaq proprietary and the compiler is no longer on the market. Thanks.

Can I know why this function is not working  

I am using Mathcad Prime Release 7.0 and Datecode7.0.0.0How do i use nesting if then statements for functions? I haven't used this product in a while and can't figure out how to break out of the initial if statement to set up a second one. Is there a guide to this somewhere? can't figure out which buttons to press 😐

I just downloaded prime 10.0 and compared the run-time to process several large data files containing a mix of floating point numbers and strings with my previous 8.0 version.  While 8.0 is already much slower than legacy Mathcad, 10.0 took 50% longer  per file than 8.0:  181 secs vs 118 secs.   I had hoped the new version would have solved the execution time issue, but apparently not.  I will continue to use 8.0 and pine for the good old days of Mathcad. 

I have plotted a beam cross section with reinforcement with the help of coordinates and calculated sectional properties accordingly.Now i want to add two different bar types in one layer and arrange them automatically and generate coordinates for them.Is it possible in Mathcad? Could someone help me?

Hello,Lets say that I have this matrix: I want to find the index at which the maximum value in the second column is obtained, and the corresponding value at that index in the first column.Like below: Mathcad Prime 9 file.

I downloaded the installer, but when I open it, it tells me "extracting" and once it's complete the window disappears and nothing further pops up.

How to convert Mathcad 6.0 to Prime 7.0? I have a few older Mathcad files that needed to be converted over to Prime, files dated back from 1996.

Mathcad Prime 9 Hello, I am trying to plot a function which has a matrix as one of its variables.  I want to plot the function as one trace so that when the matrix grows or shirks with length, I don't have to add or subtract plot traces. I made a simple example of oxygen displacement in a room with a range of different asphyxiant gas (3x1 matrix) for a given room and ventilation rate. I could display the result of all three curves by adding three traces and use the matrix index...but I want to avoid this manual step and automatic plot all the curves, let's say... when I modify the asphyxiant gas rate to be a 6x1 matrix or a 2x1 matrix. I think I've seen this done before, but don't recall where.   Thanks, Regards,  Colin

I have been performing drop testing with a product.  Collected data shows displacement during the freefall and deceleration to a stop.  I've tried several methods of data smoothing and curve fitting.  The best I have achieved gives incorrect initial velocity and acceleration.  In the image below, after smoothing (blue line), it shows an initial velocity rather an acceleration from zero.  Any ideas on how to accomplish my goal would be appreciated.  See the attached Mathcad Prime 9 document. Thanks, Bob 

Hello Community Members, I would appreciate your help in fixing the solution to a second order differential equation. I am attaching the spreadsheet I created in Mathcad 10.Thanks in advance for a timely feedback!Best regards, Peter

I have a program that I have written for a fixed time step and then advanced it for two, but obviously I want to do this for many. I thought I could just do this with a for loop but I have various matrix operations in the program and cannot get the indexing right. Do I need to convert everything to indicies? There must be a simpler, more elegant and efficient way. The program is highlighted and annotated at the bottom of the worksheet. There are some auxiliary programs at the top. I am using MathCad 14. (BTW I do have a reason for setting the ORIGIN to -N, but I do not think this is relevant). Thanks in advance for any help.

Hello I am want to use Mathcad to build  a mathematical model from several  physical formulas and later on substitute either numerical values either lower formulas. The 1st difficulty I meet  is that I would expect hereafter to get numericla result in the variable JSyst. Currently the error is "undefined variable". Another strange thing is the numerical resuls from the Solve command is not combining the unit. Is there a common explanation ? PTC Mathcad prime 9.0.0.0

Hi everyone,I want to do a linear interpolation for k in MATHCAD from this table taken from EC2.As you see, if the division c1/c2 is <= 0.5 the value must be 0.45 and if the division is greater than 3 k is equal to 0.8.How can i solve this. Nota: I'm new to MATHCAD.

Hi,unfortunately only v7 and above is still available under this link?Unfortunately my old hard disk with Mathcad v4 is broken and I still have a permanent license. How can I get a Mathcad 4.0 download? Regards  

1. Received an email for the Mathcad Express download2. Clicked on button, the file pim_installmgr_mathcad.exe was downloaded.3. Run the a.m. file. Extracting... window appeared, when completed it closed and no installation happened I have a 64-bit operating system with windows 10.  Tried to run as administrator as well.Thank you.

I asked questions in the collaboratory several years ago, and as far as I can tell, many of those issues were never resolved.  How may I get my old Q&A so I can go through them and compare the issues to the newer versions of MathCAD? 

Well it looks like the Collaboratory has died http://collab.mathsoft.com/~Mathcad2000. Not even a redirect notice.It was good while it lasted.Philip

The Problem Has this happened to you?   You are involved in the development of a new process.  At this early stage in the development, the catalyst developer has some indication of success, but there has been no kinetic study conducted.  Thus, the reaction network is only partly known, if that.  Because the development team is following the Scale Down development method (see earlier blog article), you have been assigned the task of creating conceptual process alternatives using a commercial process simulation program.  This early process study may reveal information that may help the catalyst developer "tweak" the catalyst toward the more economical set of selectivities.  Also, getting an early start on the entire process design will help prepare for more focused optimization later in the development.   For the reactor model in the process simulation, you will be using the stoichiometric reactor option.  You have been given the list of reactants

Hello everyone, I require your expert assistance in setting up a 2D parametric plot to represent the geometry of a miter bend.The attached Prime 7 worksheet contains the formulas driving the plot. Although I utilized AutoCAD to sketch the miter elbow from the results from the worksheet, I need to recreate it in Mathcad through a 2D plot. The ultimate aim is to generate a DXF of the 3D object for import into the 3D design software but my first priority now is to achieve the 2D plot in MathCAD prime.
