Mathcad

Hi There ,I have two functions are exactly the same but in two different sheet in the first sheet . it works perfectly and I’m getting the expected answers for f2In the second sheet it doesn't work and I suspect the reason is M has different arrays . How can I fix this function : the error says : This array index is invalid. The index must be an integer, not less than ORIGIN, and not greater than the last element."I can’t attached simplified sheet even in zip file. I hope you can help Thanks in advance , Yusra 

Hi. I am trying to use an advanced list box to select a beam section from the first column in a matrix that I can then use to lookup related properties further on in my calc sheet. The problem I have is that the selection does not get parsed to the output variable. Any help with this would be appreciated, I can’t seem to find anything useful online, but I am clearly missing some detail.Here is the list box code and MathCAD file attached. // TODO: Add your initialization code herefunction ListBoxEvent_Start(Inputs, Outputs) { // TODO: Add your code here};function ListBoxEvent_Exec(Inputs, Outputs) { // 1. Clear the list box contents FIRST to reset it ListBox.ResetContent(); var options = Inputs[0].Value; // 2. Loop through and add the strings for(var i=0; i < options.length; i++) { ListBox.AddString(options[i]); } // 3. Set your output Outputs[0].Value = options[ListBox.CurSel()]; //Outputs[0].Value = ListBox.get_text(ListBox.CurSel());};function ListBoxEvent_Stop(Inputs,

Hi community,I’m coping a program to make tables but get errors?What's wrong?Regards,CarlosRomero PD. This routine can be used with either vectors or your beloved ranges as arguments. First we create a function which tables a function with three arguments, so that the result is a nested array consisting of a vector of matrizes. Ever of those matrices shows the function values whith constant third argument z and x as rows and y as columns.

I would like to use the result of a quadratic function for another mathematical operation. Example: F(x)=4x^2+x-3 gives the results -1.0 and 0.75. I would like to use the value 0.75 for another operation. Please give me some tips on how to write this in Mathcad.

Hi Everyone I’m doing the same calculation in two different sheets , but I get errors in the another one although they are the same . why is that ? thanks Yusra  

Hi there , How can I work in Mathcad faster. it freezes when I use large data I have to use loop functions , however , it took so much time and doesn't calculate I have to close it and open it again and still doesn’t work  Thanks, Yusra 

pls i need this thing

Dear all, Hope everyone is doing well. I am using Mathcad Prime 8 and I am trying to find a way to convert a pdf (originally a mathcad file) into a mathcad file (e.g. mcdx). There are formula equations in that file and so far when I try adding the file into Mathcad, the formulas are not recognized. Is there any way to do this? Best regards,Vich

Hi There , I always face this error and I don’t know how to solve this . I need to find the difference between 2 levels in  same z which has 4 rows like it do the same calculation for each row separately  Than I have to find the average and minimum value for this results  I attached simpler mathcad in zip file 

How can I make sure that e_max is added correctly … non of them has units , but still getting this error Thanks Yusra

Hi,Another Odesolve problem with an error I cannot identify. Google AI says its a syntax problem but I am damned if I can see it.Any assuistance would be appreciated.Regards, Ross

PrimeConnect C++ -> Prime -> C++PrimeConnect is a pair of C++ solutions/projects.One writes a *.mcdx Prime output file fully described by C++ syntax that encapsulates the mathematics of a Prime Worksheet.Two reads a *.mcdx Prime input file where all evaluation regions of a Prime Worksheet can be assigned to C++ variables in one line each.They both work on the underlying feature of *.mcdx files that are a collection of zipped XML files.  In the case of Prime text regions zipped up zipped files of text.The underlying XML text manipulations are handled invisibly by PrimeConnect. User of C++ can concentrate on the mathematics when writing a *.mcdx file.  User can concentrate on what are all the evaluation regions in a Prime worksheet are and assign them to C++ variables.Writes Prime v10 files, Reads Prime v9, v10, and v11 files without varying C++ code just point the C++ to a *.mcdx file.Both Microsoft Visual Studio 2022 C++, and Embarcadero RAD Studio 12 projects are available.  The

Hi there, I don’t know why it shows this error here . I used the same function in another sheet and it is working Regards,Yusra

Hi there ,I want to write : if z_top,j > Hphr → use γ (unsaturated)if z_top,j < Hphr → use γsatbut I end up with this red box … the blue box is only using γ (unsaturated)can you please help me fixing this ?Thanks Yusra 

Reference topicThere does seem to be a bug with Polyroots. I get the same error with the Quicksheet and a manually entered matrix of coefficients.If anyone can advise how to fix this issue  your advice would be appreciated. Ross 

A PTC Mathcad Prime XML Writer in C++File created with PrimeWriter v1.1 Alpha, an Embracadero RAD Studio 12 C++ Builder program. Program creates a rudimentary worksheet as a starting point.  It is intended for further enhancement to create more elaborate worksheetsStarted with a simple request of ChatGPT"create a PTC Mathcad Prime file that creates variables a and b of 3 and 5 respectively and adds them together for variable c."This started a week long Monday to Sunday, long hours each day focused chat with chatGPT and has produced a simple programmable worksheet generator in C++. It has some functions already defined; operators +,-,/,* sqrt, sin, cos, tan, exp, pow, nthroot, max, min, atan2, lsolve, concat, det, trace, rank, eigenvals, augment, and submatrix. Adding a new Prime function type only takes two lines of code. So more will be added over time.  Greek symbols can be used.It is intended as a quick visual report writing method for my C++ FEM work.The new advantage is C++ progra

 I recently started using Mathcad Prime 12 for structural engineering / Eurocode calculations and I noticed something frustrating regarding the unit system.Mathcad correctly understands that: kg/s² = N/m. However when working with line loads (common in structural engineering), Prime often displays results as “kg/s²” instead of the expected engineering SI unit: N/m or kN/m.The strange part is that under “Insert Derived Units → Force per Length” there are several imperial units available: kpi, klf, plf. but there is NO SI alternative such as N/m or kN/m.This creates a awkward workflow in SI-based calculations, especially for Eurocode and structural design where line loads are constantly used.Currently the only workaround that i found seems to be manually dividing by (kN/m) , creating display variables or manually writing the unit as text. This partly defeats the purpose of the otherwise very capable engineering unit system.Questions:Is there any hidden way to add custom SI derived units

Hello All, The following symbolic evaluation used to calculate without any issues in mathcad 15. It does not evaluate in Mathcad Prime 11.0.1.0. i have attached the sheet,Regards,Sam   

Hi all,Last week we released PTC Mathcad Prime 12.0.0.0. We’ll be sharing more detail on www.ptc.com soon. A handful of users reported an issue with the release.Currently, PTC Mathcad Prime 12.0.0.0 will not run if it’s installed on a system where the system language is set to one other than one of the ten languages officially supported by Mathcad (US English, French, German, Italian, Spanish, Japanese, Korean, Russian, Simplified Chinese, and Traditional Chinese). If you run Mathcad Prime 12.0.0.0 on a system using one of those supported languages, there’s no problem. If you can change your system language to one of those supported languages, Mathcad Prime 12.0.0.0 will run fine. But if you need to run Mathcad Prime 12.0.0.0 on a system language not officially supported by Mathcad, you should remain on PTC Mathcad Prime 11.0.1.0 until this is resolved.We’ve been working closely with Microsoft on this issue and have identified a fix. We’re currently in the process of building and testi

This month’s challenge is inspired by the greatest rock band of all time: Rush! Specifically, it is in honor of the 50th anniversary of their concept album 2112, which gave us the Starman logo. Here you can see the logo along with geometry in Creo pertaining to the challenge:Starman Star Challenge depicted in Creo ParametricNote that the Starman logo is not a pentagram, and Rush is not devil-worshipping music (as many of our parents thought). Drummer and lyricist Neil Peart (RIP) was really into Ayn Rand (which is arguably worse). The logo represents a naked man, armed only with his intellect, resisting the collectivism of the Solar Federation. Listen to the album. It’s awesome.Here is the challenge: start with a circle of radius 1. Inscribe a regular pentagon. Connect the vertices to form a star.Challenge 1: Measure the area of (1) the star, (2) the pentagon inside of the star, and (3) the tips of the star (the star minus the interior pentagon).Challenge 2: Write functions for these a

In the days before MATHCAD Prime… It was possible to annotate your analysis images with “Arrow Attached Text”.  It is no longer present.  One must annotate an image in MS Powerpoint before adding image to Mathcad Prime 11.    It makes tasks much more work going between other apps for graphics.  I add alot of “fabrication” pictures to my “Material Review” packages as I structurally review” in process fabrication opportunities.   Please consider restoring and even enhancing this former ability.    Thank you.

Good morning, Community,Please I need your help, I have converted some Excel workbook into Mathcad Prime worksheet, my problem is that the AI created the file but I cannot open the file in Mathcad Prime 11. Please see attached files for your attention.Thank you
