When I find a new function and want to know what it does and what its arguments are, I go Resources > Help and enter the function name. Let's say I enter "augment". When I click search, I get dozens of hits and it takes me a while to find the one that actually explains how to use the function. Is there a more straightforward way to get right to the usage of the function? I'm using Prime 11.

Hi dear, I'm having trouble with the "for" loop when I create a function and try to graph a spectrum as a function of time.I have MathCAD version 11. It worked in the old version, but in this latest version, it shows me an error message stating that the variable T is not defined.Why is this happening? 

In mathcad Prime 1.0,is there any way to change the background color of the page?Thanks in advance.

Converting from Mathcad 14 file to Mathcad Prime 11.An error occurred when extracting and redefining a matrix by specifying a column.Changing the matrix column specification from a variable to a number does not cause an error.Why is the error occurring?

I am trying to fill a 1D array/vector with calculated scalar values. This works fine for a simple calculation; but for a more complicated calculation, it fills the vector with nested [1x1] arrays instead of scalars. I have tried to use Vectorize to fix this, but unsuccessfully.As an example, I define an array index i = -mf::mf. A simple function f_sub_i = f0 + df*i works fine to set up a vector of frequencies f with uniform step size df. But now I try a Gaussian function S_sub_i = e^{-[(f_sub_i -f0)/sigma]^2} , and I get a vector of nested [1x1] arrays instead of scalars. How can I get a vector of scalar values calculated by the formula for S_sub_i? I'm using MathCAD Prime 9.0.0.0

Does anybody know how Mathcad strings are encoded?   I've got a project on the back burner to look at Babylonian mathematics, including astronomical observations.  I'd like to convert between Arabic and Sumerian/Babylonian numbers and display them accordingly.  Unfortunately, whilst Unicode has code points for cuneiform numerals, I can't display them.   According to the Mathcad Prime 11 Help,   vec2str(v)—Converts a vector of UNICODE codes in v to a string. This function also works with zero-length strings, such as vec2str(0) = "". str2vec("S")—Converts a string S to a vector of UNICODE codes corresponding to the characters in S. This function also works with zero-length strings, such as str2vec("") = 0 v is a vector of integers representing UNICODE code points for any valid string character. Acceptable values are integers in the range 9, 10, 13, or 32 - 255. The mapping of codes to characte

I am looking for a definitive date as to when the 11.0.1.0 release became available for installation.

Can anybody throw some light on the problem below when using min?   "System Error.  Entry point was not found."   I tried rearranging the definitions of pred and pushing min further down the functional chain, but to no avail.  Indeed, using IsFunction caused Mathcad to bang out.   max doesn't have this issue.  Nor do any of my redefinitions of min.   The problem occurs in both Mathcad Express 10 and Mathcad Express 11, even when only the definition of pred and the evaluation are present.  pred has a counterpart function, succ, and that too shows the problem.     Mathcad Express 10 worksheet attached and Exception log file attached.   Stuart  

Hi I need to subtract two different matrix . one has ( 7 rows, 2 column)  and the other has (5 rows , 1 column) I know the other own is shorter so the result should be the same number in the bigger matrix. like it treat the missing numbers as zeros Is that possible ? Thank you The sheet is attached 

i had to replace the motherboard in my system, and now Mathcad 14 claims the license is not valid and will not run. I used the original CPU, disk drives, RAM, and replaced the motherboard with the same model.

how am I able to find this information?

How do I change my email address.  My current email will be void at the end of August and I find no way to change it on my profile or settings.Thanks

I need to add a summary at thr bottom of my calculation to shoe results as shown below.I am not able to do.I request shed me with some lights to get around this.

I am working on a sample to develop my calculations.I used both If .. Then and While.But, I can get the results: J is not adding up. Looks like J keeps remaining at 1. I request help. 

It mentioned problems with the server after putting in my product code so i tried again and it told me that i had used up all of my uses and now i dont know what to do. It said something about either the server being busy or something else

I'm using MathCAD 9.0.0.0. I get this error on my last equation...I don't know what's off because all of these variables worked fine together up until this point. Initially the box was only around the first CDH until I added "explicit,ALL" so that might be something to look at. Thanks,      Brent

Hello,I need to define a large number of variables, as listed in the attached Excel file.The file includes the variable names, units, and values.Currently, I’m defining each variable and its unit manually, which takes a lot of time.Is there a way to make this process faster—perhaps by using loop processing in a program or some other method? attached file is made by Mathcad10 

I have two list boxes (MathCAD Prime 11.0.0.0), The selection of one list box drives the list of the other box (see picture). The problem I have is the values update on re-opening the sheet. I can get the sheet to remember the 'Type' selection. However I can't get the second list box to remember the selection from the previous save and close. Below is the code in the jscript:- // TODO: Add your initialization code hereListBox.ResetContent();// Add Strings here as needed function ListBoxEvent_Start(Inputs, Outputs) {   // TODO: Add your code hereListBox.ResetContent()if(Inputs[0].Value=="UC"){ListBox.AddString("356 x 406x 1299");ListBox.AddString("356 x 406x 1202");ListBox.AddString("356 x 406x 1086");ListBox.AddString("356 x 406x 990");... (the full script code is attached)So I know/suspect the issue is the 'ListBox.ResetContent()' line but how do I stop the script running on open or remembering the selection, so that it keeps the previous save options?The sheet opt

Hi there,I have been trying to use the Symbolic Solver in Mathcad prime v10 as shown in the following SS but I could not figure out. Could someone kindly plz help in this one? I would be much obliged. I am trying to get the values of Wa and Wb using the symbolic solver. 

Hi, I am a new user of Mathcad Prime 10, with some experience of Mathcad but all gained long ago, before Prime came along. I have set up some functions to operate on range variables with equispaced input values. I want to work with the resulting range variables but have hit problems, partly due to a general lack of understanding and maybe partly due to the known limitation of Prime 10 https://www.ptc.com/en/support/article/CS416474 -- corrected link I can plot the output vs the input on an XY plot and the values check out correctly. To export the resulting XY table to Excel, I tried to use https://community.ptc.com/t5/Mathcad/MathCad-Prime-9-0-Exporting-data-set-Excel/td-p/913932The input/independent range variable is recognised and entered into the Excel cell. The output/dependent range variable is not recognised. I have also tried various "range to vector" conversions but these all seem to have the limitation of only working on the input/independent

My version of Mathcad 9.0.0 suddenly refuses to acknowledge my active license information. The license should be valid at least through the end of this year and was working fine last week.. I have gone through the process of retrieving my license file from the PTC dashboard with no success. This is very disruptive and I need this resolved quickly.

for a range variable k an assignment variable cannot be set, Kindly help, see the attached worksheet please. Kind regards

Hello,I am located in Finland and I cannot install Mathcad Prime using the online installer (the PTC Mathcad Prime 11.0.1.0 box remains greyed out and cannot be selected).Could you please provide me with a direct download link for the full offline installer of PTC Mathcad Prime 11 (Full Package)?Thank you very much for your help!Best regards,Turkan Genc
