Mathcad

I converted a file from MathCad 15 to MathCad Prime 9. After the converting was made, MathCad Prime 9 is marking some of the variables with red Box saying that this variable is not defined (See screeshot). I noticed that the Problem is that Variable contains two level of subsripts and Mathcad Prime 9 cant see the second subscript. As a result all Variables will be seen as only one variable and not multiple diffrent variables. Can someone help me please? Thank you Greetings

Hi, 1. How can I search for each frequency range?For example I looked into the excel file and I saw that 1kHz begin from line 61536 and is ended at line 62560: ... Therefore I extracted manually the respective range in Mathcad:       So, for example I want to know between what range the 0.001Hz begging and ends, but without staying and looking into excel file, some automatic routine if can be made in Mathcad:   And then I want to know the maximum value for Vout and Vin at the respective Frequency and at which time these maximum values are occuring: Above its only the maximum value at 1kHz, but I do not know at what time these maximum values for Vout and Vin are occuring. Because I want to know then the difference between t2-t1.

In old Mathcad versions, the program performed calculation step by step, during the visualization of the page. Thus if you changed the value of a variable that was involved in a lot of formulas in the sheet, this action did not lead to a lot of calcs that you didn't need in that moment but only to the ones that you were interested in.Prime versions, perform all the calcs where the variable is involved, even those you are not visualizing and therefore are useless for you in that moment.This behaviour is strongly disappointing for long spreadsheets, where old Mathcad versions are much more satisfying.I wonder why this this behaviour has been changed moving from Mathcad to Prime. In any case Mathcad Prime, after ten years of developing is very far form the performance ad usability of the old Mathcad

Hi, i have the follow system of 3 equations i need to find the operating region for the system where vrd, vrq, Re, Le, Nc, Cdc and w are constant parameters, Md and Mq are parameters that i can change and i want to introduce in the system to get all the Isq, Isq and Vdc solutions. In resume, i want to vary Md and Mq and get the corresponding Isd, Isq and Vdc for each par of Md and Mq input, anyone can help me with this? i will be very gratefull. PD: Sorry if my english is not so good.

Hi Folks, Here's a problem I saw on Dell laptop a while back and now have on my new desktop - a Dell running Windows 11.  I made a simple function of x and y.  It looks fine as a contour plot, but the 3D plot won't render.  Has anyone else seen this? This is the only graphics related problem I've had with either machine, so it doesn't feel like a driver issue. Thanks for your attention 🙂 Mark  

I have several measured data sets.  Each dataset will result in a curve with y-axis (ordinate) is its magnitude (in dB) and with x-axis (abscissa) is angle (in degrees).  There is fairly large equal spacing between points along their respective abscissa axis, and with accuracy important for this work, interpolation was necessary.  I chose to work with a cubic spline to avoid the Runge issue near boundaries.  As you'll see in the attached worksheet, each curve is not perfectly symmetric about zero.  Some peak near zero, and some curve's peak is much further away.  The goal is to automatically determine an accurate estimate of the angle where the curve's value is 3 dB below the level of the maximum.  There should be two such angles - one on either side of zero.  Unfortunately, I'm having difficulty making the symbolic solve and/or solve block to work on just one dataset.  But the goal of course is to potentially program this to autom

Hello everyone, I am encountering difficulties setting up a 2D interpolation in Mathcad. My objective is to determine the parameters A, B, C, and D for two given inputs: ratio "r" and delta "δ." The dataset is categorized into four groups based on Ratios: 0.25, 0.5, 2, and 4. Each group is associated with a specific set of Deltas and corresponding parameters A through D. While I have managed to interpolate within a single Ratio group, my challenge arises when attempting to interpolate for a ratio value that falls outside these defined groups, such as 3.5. Attached is my Mathcad Prime 7 worksheet for reference. I appreciate any assistance you can provide. Note: When the delta input "δ" exceeds the highest Delta value in a given Ratio group, the output should correspond to the highest Delta record's values, as extrapolation beyond this point is not allowed.  

I was looking at Wikipedia to find out if a given type of matrix had a particular name (like the Zero or Pascal matrices do).  At the end of one article, there was a link to the category of Array Languages, so I had a quick look and ... Mathcad wasn't on it.    In fact, there are are a plethora of places, inside and outside of Wikipedia, that I would expect Mathcad to show up, but it rarely does.   Even the Infobox on the Mathcad Wikipedia article isn't up to date - it's showing Prime 5.0 as the latest release.   I was wondering if PTC's marketing people had any kind of remit to keep the most common websites, etc up to date and to ensure that Mathcad has a reasonable web presence?   Stuart   PS. I added Mathcad to the Array Programming Languages category (plus about a dozen more). Does anybody know if there's a special name for a matrix of sequential integers?

I received 2 license files and I tried both. (No difference.)I configured the license (pointed to one of the 2 files) and I got this:But then when I run Mathcad, it acts like it has no license:What's going on?

I am trying to configure the Trial license version for Mathcad Prime 9, this is the error message I get when I try to configure using the file I received via email:Failed to configure license for PTC Mathcad Prime 9.0.0.0: Access to the path 'C:\ProgramData\PTC\Mathcad Prime\MathcadPrime.exe.V7.config' is denied.

Dear community,   Unfortunately, I have no experience with numerical integration. Now I am confronted with this problem (detailed description in mcdx). I hope that one of you can help me to solve the problem.Many thanks Michael

This is an indication I would say irrelevant, but in any case it may be of particular interest to chemists: there is a printing error relating to element 110 of the table of elements presented in the M-15 help: it is Darmstadtium and not Darnstadtium.

I am trying to solve a simple expression using a solve block with units.  By inspection, all the units are consistent and the solver should work, but I get a message "These units are not compatible".  Any assistance in getting the syntax/format correct would be appreciated.

Good day everyone! I am new to the forum, and I am a student of electrical mechanical engineering, I am studying a tutorial about the integration of Mathcad and PTC. I think it will be a very useful tool for my career and professional life. I share the following link. I have a question about the availability of the file that appears in task #1 SPRING. MCDX   Link https://learningconnector.ptc.com/tutorial/1637650665404/integrate-a-mathcad-prime-worksheet-in-creo-parametric   If you could help me by clarifying this question, where can I download it?

Tells me I have reached the maximum number of licenses. I have prime 7 exress and would like to install prime 9 express. It keeps asking me for some license everytime I install the free version. I also cannot load the knowledge articles below. The links don't work, it jsut does some funny animations and does not load the community pages.

hi -I'm trying to plot a function but I get an error.Not sure how to construct this properly. Any help is very welcome. 

Dear Specialists, I am a using Mathcad Prime 3.1 .Ink I want to confirm attached xmcd file, but I can't do my version. Could you please tranform this files? Best regards,Niko

Does anyone know what the problem is in this Mathcad 15 sheet using the linterp function.  I have successfully used it exactly this way before.  All I did was change the input data.Attached is the xmcd file: IEC HEMP E3 STANDARD INTERPOLATION.xmcd.This sheet calls another xmcd as a reference: POINTS PER DECADE FUNCTION.xmcdI have attached both files along with the data file. The error claims that the vector Time is not in ascending order.  You can see from the data and the plot of Time vs Time that is not correct.  You can also see that the more dense t vector is ascending and on top of the Time vector. Thanks for any help provided.

Hi everyoneI am trying to automate a task, where the user has to select a sketch (that will be graphically shown using a GIF-Image stored somewhere), then provide certain inputs (namely dimensions) that will be shown on the sketch and then my worksheet will compute the results.  To provide an example, I could say:Sketch:= Square / Rectangle / Circlefor "Square" the input variable could be: a (the side of the square)for "Rectangle" the input variables could be: a,b (the two sides of the rectangle)for "Circle" the input variable could be: r (the radius).then MathCAD would take the input variable(s) and compute, as an example, the perimeter and the area. The computation is no problem at all, I can manage it with some ifs.  But the input variables, I do not know how to "force" the user to input all and only the variables that are needed for the chosen sketch (the number of this variables is around 8-10 in my real application, the geometrical sketches being slightly more

Is it possible to display a matrix as an image (as was possible in Mathcad 15)?

I've been running into a repeating problem with the output equations on embedded Excel spreadsheets.  The visual width of an embedded spreadsheet is limited by the width of the input and output expressions.  Because of this, I organize my I/O equations carefully.   Sometimes, I find that my spreadsheet is now wider than the page it is on.  If expand and look at the output equations, they are spread out and staggered across the page.  Not at all like I left them.  Blow is a screen shot.  You can see that they are plainly staggered wider than the page.It should look like this.Does anyone have any ideas what is happening.  This is a repeating problem across several documents with embedded spreadsheets. 

start at once to define functions for tensor calculus. This is something that mapple already does. Guys, don't fall asleep.Thanks.

When are you going to define the bit and byte unit? you cannot generate them from other units.Thanks

Well, the gamma function presents a problem in mathcad that makes it difficult at first sight to apply it to concrete problems in comparison with other languages like R or Python.This problem is that the gamma function in mathcad has only one parameter (it seems to me that their engineers do not corroborate their pre-made functions with wikipedia). The gamma function requires 2 parameters: 1) the shape parameter: s 2) the rate parameter: r.After racking my brain for many hours I came up with equivalent formulas in different ways:For probability density function (pdf):1) with the direct formula.2) adapting the density function given by mathcad:pdfgamma(x,s,r):=dgamma(x*r,s)*rFor the cumulative probability function (cdf) there are three ways to do this:1) define the incomplete gamma function and then calculate the cdf.2) use a serial form3) defining a new function with the one already given by mathcad:cdfgamma(x,s,r):=pggamma(x*r,s)Regarding the generation of random numbers the following
