Mathcad

As per this thread - same issue   Hi Luc Meekes I have probably the same problem. I have renamed the png files but I do not know how to correct the reference to it. It is also a very important file for my diploma thesis.  Thank you so much for your help!

What can you say about it? From one my artice: "Operations of dividing a second-order differential equation into two first-order ones, transferring mass from the left side of the equation to the right side, turning a set of points into a function by interpolation, and so on. in Mathcad 15, the built-in Odesolve function automatically conducts, paired with the Given keyword. This function appeared relatively recently in the Mathcad environment and is not yet available in the SMath environment. The process of solving differential equations with Odesolve can be compared to driving a car with an automatic transmission. Working with the rkfixed function and others like it is driving a car with a manual gearbox. But real car enthusiasts (almost pros) prefer a car with a manual gearbox, which allows you to drive more professionally and save fuel." Gravity train with two kind of friction.

I have two questions about the attached worksheet:1. I am trying to calculate two functions in two different ways: One by using a program, the other using the step function. The program gives expected results and  for one of the functions, the step function expression agrees. For the other, it does not. Obviously, I am doing something wrong, but I cannot see what it is - I  thought I set them up in the same way.2. When I eliminate an argument from the function, that I do not think is used, I get an error with "augument". This is something else I cannot understand.

Good afternoon, As titled, I am crafting a general purpose ShellExecute that will run inside Prime.  I have it working.  But there is an issue with a null pointer.  My approach was to pass strings.  These are strings that define the EXE, and the command line.  An example would be like this: ShellExecute ("Notepad.exe", "c:\\data\\test.txt", "Null") The problem is that I had an issue with a null pointer being passed, so I had to create three MCAD strings like this:  LRESULT ShellExecute_MCAD(MCSTRING* pMCS_Empty, MCSTRING* pMCS_Process_EXE, MCSTRING* pMCS_Process_CMD)  here is the Visual Studio cpp file.  I can also attach it if needed.  // dllmain.cpp : Defines the entry point for the DLL application. #include "pch.h" #include "MCADINCL.H" LRESULT ShellExecute_MCAD(MCSTRING* pMCS_Empty, MCSTRING* pMCS_Process_EXE, MCSTRING* pMCS_Process_CMD) { // Routine performs a MCAD shell execute HINSTANCE L_R

I am unable to get a proper plot in mathcad prime 

As per the original Post..    Luc…   This is very interesting and elegant.  It turns out that I have an application for your method as well.  However, I have Prime 5 and can't read your Prime 6 file, and the image you posted is cropped on the right end.  Could you post a full image so I can recreate your solution in Prime 5?  Thanks.   Fred

Is there any quick and easy way to generate Binomial coefficients with Mathcad 8.0?  Or do I just use the definition?

Will be good!? Not 13 but 12!

I have an array with values and I want to extract the rows, from a different matrix, that correspond to the values of the array. Any ideas on how that is possible? Right now the row extraction command (CRTL+SHIFT+r) will only accept integers. Thank you in advance

Why I am getting solution in terms of  ω 

Not points but numbers of the points!

Any help gratefully received,I am attempting to plot an XY graph of a polynomial equation including x and y values, (e.g 4y+3x=10). cant find any help on any PTC guides and youtube drew a blank.completely out of ideas now, everything tried just throws a variety of red error boxes. many thanks in advance. BTW, using prime 8

Hello, I have a formula which defines water-pressure on a surface depending on depth and wavelength. To find the total force I have defined an integral. I want to find the depth beneath the water level where the resultant is located. I can do this manually by guessing values but I would like the program to solve this for me.  The only variable here is the depth for what I'm understanding by looking at my functions. Can someone help me understand what I'm missing in the attached calculation?  Regards/Tobias

Hello all, Does anyone have a suggestion for the following... I have a 170 page calculation, predominantly systems of linear equations, that has over 150 different inputs. What could be recommended as the best method for inputting the variables? I've tried utilising the excel component but it kept crashing.I've lumped them all into a matrix, this worked okay.I attempted to WRITEEXCEL them as they are being used elsewhere but it crashed the system.I am currently using loads of individual READEXCEL's but this is not ideal as it does not pick Excel variables (cell location cannot be moved). I'm thinking that a CSV intermediary between Excel and Prime might be best with use of some VBA, not sure. I'm in the slow process of re-writing the sheet so that logic can take care of some of it!  Thanks in advance.

How do I use the CWD path in WRITEEXCEL command   

Hola a todos, acabo de actualizar a la versión 8 prime y ahora no puedo encontrar el vector de respuestas.¿Tengo que usar el bloque de resolución obligado? personalmente me parece más cómodo la herramienta "solve, x"  Hi everyone, I just upgraded to 8 prime and now I can't find the response vector.Do I have to use the forced resolution block? I personally find the "solve, x" tool more comfortable  

Can you please tell how to solve a system of ode in prime ? Also a single ode with Laplace in mathcad prime 6?

After embedding excel component within worksheet when an input is provided the excel convert it to SI system if the unit system is set to USCS any suggestions?    

HelloI am trying to copy a matrix that is used to look up structural shapes from Prime 8 to Excel so I can update/add information, then copy-paste back into prime. Is this possible?

Hello,I would like to get a program in Mathcad that: given being a function with a certain number of parameters and a certain symbolic expression, f (p1, p2, p3, p4, ..., pn): = a certain symbolic expression that involves these parameters: p1, p2, p3, ... ,pn, to automatically obtain the following:1.  Symbolic calculation of: 2. Numerical calculation of:Given finally the numerical values ​​for the parameters: p1, p2, p3, ..., pn, calculate the numerical values ​​for the expressions of the derivatives from point 1.Example for the case with 3 variables: p1, p2, p3: 1. Symbolic calculation: 2. Numerical calculation The idea is that I want a Mathcad program that calculates automatically what I want regarding the two points above (point 1 and point 2), meaning to give me as output both the symbolic calculations and the numerical calculations, in the form of parameters, as shown for example in the example above (Sp1, Sp2, Sp3, Sp4, Sp5,

I am trying to use Odesolve. I think I am solving the same equation written in a slightly different way, but in the second way I am getting an error when I try to plot the solution.

I'm currently doing some calcs on the land-speed of a vehicle. From my other calcs, I obtained the wheel-motor's speed in RPMs, and the tire diameter. However, when attempting to obtain the speed from MPH, the calc seems way off. I did it by hand and used an online calculator. and they both gave the correct speed. What am I doing wrong, and how do I get the correct speed calc? 

Hi,I'm somewhat new to mathcad and trying to solve an equation with a solve block. (see attached)Tried several things, but without succes, I don't know if ti actually can work? perhaps with a for-while loop?The equation is quite straight forward with some forces and lengths, resulting in a summed moment, for which I would like to find a 0.  Can anybody help to achieve this or help me in the right direction? Kind regards, Casper

Dear all,I would like to extract the results from my Mathcad Prime run into Excel, but I’m not able to do so. I looked at the PTC community page but all suggestions given there do not work for me. I think it has to do with the way I run my calculations: I integrate in steps of 200 iterations and store intermediate result in a matrix and run the whole thing 'pmax' times (thus total number of iterations is 200 x pmax).I would like to extract the output from a certain row and column of matrix for different data points (1..pmax) and export this to Excel. For example, I would like to extract (Yt_ii)1,3 with ii := 1..pmax. Hope anyone can advise.

Is it possible to to index the summation for odd numbers in 15?
