Mathcad

I am using CFFT for calculations in Mathcad 14. Mathcad Prime 10 recommends using dtf rather than CFFT. However, CFFT and dft have different scaling. Could you tell me how to change the program to change from CFFT to dft and get the same calculation results? -------------------------------------------- Translated text from Japanese to English using google translate -  Subject - CFFTとdftの関係 Body - mathcad14でCFFTを使って計算しています。mathcad prime10ではCFFTよりdtfを使用することを推奨しています。 しかしCFFTとdftではスケーリングが異なります。 CFFTからdftに変更し、計算結果を同じにするために、どのようにプログラムを変更したらいいか教えていただけませんか？ -By Community Moderation Team --------------------------------------------

Hello Mathcadeers,I am familiar and comfortable with legacy Mathcad (Mathcad <=15). But since it is no longer supported, I feel that I need to migrate to Mathcad Prime 10 (learning it). I am wondering if you guys can let me know what you think. Is it worth it to migrate to MP10 (need to spend some time to learn and get familiar with it), or just stick with Mathcad15? My laptop is Windows10. Thanks so much.  Ak

Hi, I have a problem connected to explicit, ALL and programming operators. I have made two variables with programming. And I would like a second one to show (with explicit, ALL) the function it has been using to get this value. Is it possible? Am I doing sth wrong? Also, how do you get rid of that green girth? 

I am fairly new to this software and would like to understand if there is any better way to perform the things that I am trying to do my belief is there should be some way I am not just getting that  Could someone from experts help me to make the content small and cleaner ?

I am using Mathcad Prime Release 10.0 and Datecode10.0.0.0I am working on a design sheet and as part of the sheet I am including a design methodology write-up. I am using a numbered list and the write-up is too large to fit on one page. I split the write-up over 2 pages but the numbered list restarted at 1. on the second page of the list. Is it possible to set a number value for the numbered list on the second page that continues the list from the first page?Here are the errors that I facedNone

Windows 11 will be released as early as next month.  Has anyone done some testing of the existing versions of Mathcad (i.e. MC15, Prime 3-7) to identify issues under Win 11.  Personally, I have a perpetual academic license for MC Prime 3.1, and as a retiree, I am loathe buy a subscription version.     Furthermore, I have had to reinstall MC Prime 3.1 several times and it has never been an easy task.  Unless I am reasonably certain that an upgrade to Win 11 will not be an issue for Mathcad Prime 3.1, I will simply stay with Win10.   thoughts?Mike    

Hi everyone,  It has been almost a year since I started working with mathcad and I'm delighted to be part of PTC community. I enjoyed posting and discussing many of the challenges I faced while working on mathcad .  I would like to thank you all for your help.Especially @Werner_E you almost helped me in all my questions and I learned valuable things from you. I can't thank you enough. Also @StuartBruff I really like your way of replying and the effort you put to convey the information.  Wishing you all  and your loved ones a year filled with happiness, health, and prosperity. Thanks Yusra 

Hi there!I'm trying to solve, in general, one equation that is important to me.The idea is to find through my Mathcad Prime 9.0.0 the extremum value of a parameter in symbolic representation. Here, I faced some "wall barrier" for solving due to the famous discouraging phrase as "The symbolic result returned is too large to display"... What was previously done:1. The simplification of each step of the calculation formula was performed, but the final point was to calculate the Zee matrix... Mathcad didn't want to represent the particular calculus step, and I was deeply stuck, with no idea how to solve my issue. My objective in this step is to solve the derivative equation when I set the k1 value (Internal area heat capacity) equal to zero by only two variables (width of the layers d1 and d2, respectively)  to find by such derivative equation to obtain a maximum of k1 value in the general case depending on two variables (width of the first layer d1 and d2 res

I am exploring solving equations.Took a utube video.My workng file attached here to.I would like to get around this issue,Pl. help. 

This feels like the right time to publish some of the work I've been doing, on and off, over the past year.Prime Express is the free for life edition of Prime. And because it's free, it's crippled with respect to the full edition that is itself more or less crippled with respect to Mathcad. Numerous functions in Prime are declared 'Premium' functions, and they will not work in the Express edition of Prime. Among those are some very sophisticated functions like rkfixed (numeric approximation of differential equation) and polyroots (find roots of a polynomial), dft and idft (forward and reverse discrete Fourier transform), but also ordinary functions like Re and Im (real and imaginary part of a complex value), mean and stdev (of an array or matrix). Mean and stdev... Premium functions - Seriously? It's a joke! In the attached Prime 4 file, all of the functions named above, as well as many others, are implemented. This includes all of the Bessel functions, and probability distribution fun

Hi,I am doing something wrong in Mathcad? Or maybe the reference plot is wrong?     Prime 10

Hej Guys, i am new to Mathcad and not very familar with it i have a worksheet with some functions and no i wanted to use the solveblock to find some solutions for me but i have no idea how i should write it down.i added  the worksheet with the functions. i have a function with two Variables that where i want to find those two variables when i only know one result of the two out put results that the funcions brings me.the constraints i have and the expted result i put to the worksheet. maybe someone can give me some advise on how the solveblock need to be set up for a function with two variables? Kind RegardsMarkus

Hello I have a written two programs which are very similar. However, when I am running the second program, I get an error message saying "these values cannot be compared".  Unfortunately, I can't figure out what is wrong with the script. How can I solve this error? Thank you for your support!   

Hello! I am having an issue with Mathcad solve block. This is for an Electrical Engineering class, and I am trying to solve a system of 6 equations to find 6 unknown values. I have re-formatted my equations and the solve block many times and cannot tell what I am doing wrong. Any help would be greatly appreciated!

Hi, I have a long equation that I would like to break in explicitly, ALL; however, I don't know if that is possible. Any suggestions?  I am currently using Mathcad Prime 8.0I appreciate any help you can provide. 

Me and my mate are doing a school project and the file he saved doesn't open anymore on either of our Laptops. Can anyone help please? 

Hi everyone, previously I asked how to plot many arrays in one plot and I got my answer. Now I'm trying to plot the results that came out from those arrays .. however it shows some errors ... my previous question was in this thread >Solved: Re: Defining the layers - PTC Community Now, I'm trying to use  the same steps  but it show this error What I'm trying to do is to plot the results of Rb each array separately.. so I have 15 trace drawn Rb is the horizontal axis and ztips is the vertical Thanks in advance 

xx: After a while, I am using the Mathcad Prime. Yesterday, I found that the range variables not doing well in case I use step less than 1. Otherwise (for example, 1.25, 2.1, etc. are OK).Essentially, I want to specify step < 1>I would like to how to get around this issue.PL. Help. Mathcad Prime 10.0.1.0

The same program takes longer in mathcad prime10 than mathcad14. This program uses arrays in particular. So I got the following information: "The most efficient way to use computer memory when using matrices is to pre-allocate the matrix. To do this, assign 0 to the last element of the matrix. This ensures that there is enough memory for the remaining elements of the matrix. If you dynamically allocate a matrix by filling in the elements of the matrix from the smallest subscript to the largest subscript, it will take longer to calculate and the worksheet will calculate slower." But I don't know how to improve it. Can someone please help me?   Translated by the moderation using Google Translate -----------------------------------------------------------------------------------------------   同じプログラムでmathcad14よりmathcad prime10のほうが時間がかかります。 このプログラムでは特に配列を使用しています。 そこで私は次の情報を得ました。 「行列を使用するときにコンピュータのメモリを最も効率的に使用する方法は、事前に行列を割り当てることです。このためには、行列の最後の要素に 0 を割り当てます。これによって、行列の残りの要素に十分なメモリが

Hello,I want to find a way to replicate the function of logspace but using numbers, log function, usual math operators only.  

I’m currently working on a worksheet in Mathcad Prime 9.0 where I’m evaluating several functions that generate around 100 rows of values each. I have three different functions, and I need to send these values into an Excel file so that they are neatly aligned across columns. Specifically:I’d like the results from the first function, f(a), to begin at cell A1 in Excel.The results from the second function, f(b)  should start at cell B1Similarly, the results from the third function, f(c), should start at cell C1.I’m trying to figure out how I can use the "Write Excel" function in Mathcad to send these values across the respective columns in the same sheet.Due to the nature of the data, I’m unable to share my worksheet directly, but I would greatly appreciate a sample example or any guidance that can help me achieve thisCheers,Frank

Hi there , I want to remove NaN from a nested matrix so I can find the average . I tried to use (filterNaN) function but it shows this error I wrote a program to remove NaN ,, but it does nothing (page 3) in avg sheetmy goel is to find the averag without the nans >> because in my original sheet all the average valuse are  shown as NaN this is on page 22@StuartBruff Stuart >> I'm using the mean function you showed me in this thread:Solved: Re: average value - PTC Community
