Mathcad

I want to solve three equations with three unknowns and display the solution on a 3D graph with two points - the roots of the equation.I can’t find Vyacheslav Mezentsev’s utility (Mathcad 15 or Prime) for such drawing two close surface. Help please.

All the variables are defined , However I couldn't figure out why it is not working 

Happy New Year!     This month’s challenge is based around statistics, specifically permutations and combinations around shuffling a deck of cards. It’s inspired by this article: https://www.mcgill.ca/oss/article/did-you-know-infographics/there-are-more-ways-arrange-deck-cards-there-are-atoms-earth   Your challenge, should you choose to accept it, is to perform the following in Mathcad Prime: (Basic) Calculate the number of ways to shuffle a deck of cards. (Standard 52 card deck, no Jokers). (Basic) Calculate the number of ways to shuffle a deck of cards if the suit (heart, diamond, spade, club) doesn’t matter. Calculate the number of ways to shuffle a deck of cards consisting of just the face cards (jacks, queens, and kings). If you could shuffle the deck one time a second, how long would it take to shuffle each possible way? (Express the result in hours, days, or years, whichever is easiest for people to grasp.) How long would it take to shuffle the face cards until

Similar routines also were posted here from time to time and a command like this should be part of Mathcad/Prime out of the box. Unfortunately it isn't. I see that the topic is from 2016 and it is now 2024 but i had basically the same issue. Have i to conclude that it is still not fixed to create easy a vector in some range?   ----- Initially posted in this topic

Dear ladies and gentlemen,   We have 2 Mathcad licenses, but I can't find the product code for them right now. If you need any more information from me in this regard, please let me know.   We currently have the situation that we have 2 licenses and had to change the MAC addresses for them and reinstall them at the same time. Now we are faced with the issue that Mathcad 15 can no longer be licensed with the current licenses because Mathcad is too old.   So my question to you is, do you still see a possibility of getting Mathcad licensed despite a new installation, or are the licenses no longer usable for us in combination with Mathcad?   Thank you very much for your effort.   R.

I need to calculate the bearing capacity of the soil for pile foundation/ How to make MathCAD choose the minimum value always when it goes through a set of values. and there is not a certain minimum value, but it has to choose from the listed until a smaller number appear?

Hi,  I am looking to solve for F2 in the below image, Can anyone help on how to get this working in MathCad please?  

Hello,I am using Adams to solve the differential equations as below but failed, may anyone could suggest how to solve it or should I use another equation.The error can only disappear when x was deleted in the equation..,x from 0 to 10000 Thanks in advance.PW

Good morning to all,I have a matrix that works well in Mathcad 15 but provides wrong values in Prime 9.0.I only converted the matrix from Mathcad 15 to Prime 9.0, which did not work well in Prime 9.0. Even though it does not mention any error in Prime 9.0, It simply does not provide the right matrix elements in Prime 9.0.The files below Matrix Right (the one in Mathcad 15) and Matrix Wrong (the one in Prime 9.0) are the two files I am talking about. Any help will be very much appreciated. regards,  Rogelio

I am trying to write a code in Mathcad Prime 9.0 to make a K matrix by making the K0 matrix of zeroes populate with k matrix numbers as shown below and in the file attached. If anyone could please help me with the Mathcad code for that it would be much appreciated! (P.S. I do not have any experience with coding therefore I am not even sure where to start) Here is my mathcad:           This is what the K matrix should look like and it should be able to work for any n value

Dear Community Members, I've been working on a Mathcad function to exchange rows and columns of a square symmetric matrix, and I would appreciate your feedback on its correctness.I tried but it gives an error. The png file has the problem and the Mathcad has the solution that I tried. Thanks for the help. AR

If I have a vector A and B both with 10 elements. How can i create a vector  C that has the minimum values of A or B on each corresponding position.Thanks in advance !

I am trying to combine a few load cases (speed and loading combinations) into arrays (or matrix), see simple example of input and what I'd like to achieve. I know how I could use nested FOR to loop through the arrays but I don't know how to assign variables to get the end result. Or is there a different way? I hardly know anything about functions and programming in Mathcad. 

Hi, I have a MCP sheet that pulls from some matrices to perform basic calculations that takes over an hour to complete. I would like to improve this significantly if possible. I tried to rely on built-in functions (e.g., "lookup") when possible for calculation efficiency. The main calculation (image below) uses data from three matrices (36177x9, 2412x9, 1206x12) to perform basic +-x/ calculations resulting in a 216619x8 matrix. At the end of the sheet, there is some red text that helps point this out. File attached. If anyone has tips for how to improve calculation speed or is able to help me optimize this process, I would much appreciate it! Thanks!AndrewMathcad Prime v9NO multithreading11th Gen Intel(R) Core(TM) i5-1145G7 @ 2.60GHz 2.61 GHz24.0 GB64-bit 

I had to install MCAD 14 on a new machine. To my great surprise, that went well, except that I cannot access QuickSheets. When I try, I get the message below. Can anyone help with this?  

Have been working on a file for a couple of days, but crash resulted in 0kb file! Is it possible to recover/restore the file??

Using Prime 9.0Hello,I have a large matrix of time and current data for 6 different channels. The even columns (0,2,4,6,8,10) contain the time data for the odd current data columns to the right (1,3,5,7,9,11) - Excel image shown below for visual clarity.I am trying to sum up the current data of the 6 channels into a 2 column matrix (time, current) adding the currents at the appropriate times. The time data is in microseconds with time steps of ~.006-.007 μs and the channels time data overlap with start times shifted by 7.5 μs. For example, Channel 0's time data spans from 7.5 μs to 41 μs, Channel 1's time data spans from 15 μs to 48.5 μs, and so on. I wrote the matrix data to an excel file and attached. Excel Image:MathCAD matrix:It's kind of hard to explain verbally, but basically the channels have time and current data that overlap, and I want to add the currents of the overlapping times accordingly. I have a user-defined function tha

 Is there any way to simplify this? 

I announce a competition - who will create the most interesting and beautiful portrait of the roots of two equations. I will send a hard copy of my book (2⁵ Problems for STEM Education - 1st Edition - Valery Ochkov - Rout (routledge.com)) to the winner of the contest. The end date of the competition is April 1, 2022. I will personally determine the winner. Materials explaining the essence of the task, in attachment. In the picture - a sample of a work of science and art, which should be submitted to the competition.

Even though the function is defined when doing ans := ShahST(G), MATHCAD says its undefined. Please advise. Thank you in advance.

Hi! I'm a college student having problems with the creation of the matrix. The informational failure is "Found a similarity while evaluating this expression. You may be dividing by 0 or inverting a similar matrix." Please help! 

Hello! I just created a new account with my university email account, then when I set up mathcad Prime it gives me error of: "You have reached the maximum number of license requests available for your product type." Please help me with this issue. Thank you

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0Retype serverlicense adressHere are the errors that I facedHi,We have users that needs to retype the serverlicense-adress once or every other week, it is like the program don't remember what you typed in.All other functions i working so it is only this that we have some issue with, have been so since summer.I have the program also installed but don't seams to be an issue for me, but i don't use the program i that way, i just maintained the server and our license.Have you heard about this before, do you have some recommendation what we could do?Best RegardsTomas EklöfService Responsible
