Mathcad

I am trying to create phasors as per :Synchronized sampling and phasor measurements for relaying and control - Power Delivery, IEEE Transactions on (tamu.edu)  (Pdf attached) Checking to see if my mathcad implementation is correct Thanks.   

Thanks.

Many years ago, I recall needing to install some SW (VB commondialogs or such?) in order to have real time active controls, e.g. scrollbars, function correctly in MCD11. If I documented this process, it appears to have been in write-only memory. I wasn't able to find the ancient references by searching here either. Anyone remember what needed to be installed, and the process? I seem to remember that RichardJ was a key resource at that time.Thanks,Lou

Dear Stuart or other power user,You mentioned that beside of mathcad you also experiment with maple. As I stick to real mathcad I would like to have a plan B for the moment my mathcad no longer works. So I am transferring some of my mathcad sheets into maple as exercise.In the attached worksheets I believe that I did exactly the same in both programs but the end result is 10 units lower in maple than in mathcad. I have tried to find the reason for days but was not able to pinpoint the issue. Would you be so kind to throw an eye on it? As the maple file could not be uploaded I provided it as a txt fileI already want to express my gratitude in advance for your help.Filip

can anyone please convert this file to latest mathcad prime supporting file

How can solve problem in attachment?

I would like to use genfit to fit a function with more than 9 parameters, and its not clear to me how to do that.  The web description page for genfit says: • vx, vy are vectors of real data values of the same length, corresponding to the x and y values in the data set. There must be at least as many data points as parameters.• vg is an n element vector of guess values for the parameters. If n = 1, then vg is a scalar.F(x, u) is a fitting function, or a vector of functions, where x is the independent variable and u is either a vector of parameters or individual parameter names. The following equation is both a valid representation for a fitting function:• n is a positive integer. In the case of non-vectorized parameters, there is a limit of nine individual names. For 9 or fewer parameters, just including the parameters in the fitting function definition as F(x, u1,u2,

I am using Mathcad Prime 7.0 7.0.0.0With an VisualBasic Programm we extract Calculations out of MathCAD 15.0into an Excel Table.I managed to transform the file from MathCAD 15.0 into MathCAD Prime 7.0but the extraction of the values does not work.I managed to open theI changed"GetValue" -> "InputGetValue"and"getelement" -> "GetMatrixElement"but the values still do not get transfered to Excel.What is the right syntax to adress the values in MathCAD Prime?(mcws stands for MathCAD-Worksheet)VB-Script-Line for MathCAD 15.0:Set MC = CreateObject("Mathcad.Application")Set mcws = MC.Worksheets.Open(pfad & Worksheets("Stammdaten").Range("MCDatei"))...WertEinlesenMCAD.uwrk = mcws.GetValue(varname).getelement(0, 0)Script for MathCAD Prime 7.0:Set MC = CreateObject("MathcadPrime.Application")MC.Visible = TrueMC.ActivateSet mcws = MC.Open(pfad & Worksheets("Stammdaten").Range("MCDatei"))....WertEinlesenMCAD.uwrk = mcws.InputGetValue(varname).GetMatrixElement(0, 0)

I am trying to achieve result with units however as soon as I input the units the answer changes Am I missing something 

Heya, I've been looking everywhere, I've been following basic plotting tutorials, but I cannot for the life of me find a way to plot my function. Each time I try I just get a single point on the y-axis. Any help would be incredibly appreciated.  

Hello everyone! This book is free to read as a Kindle on Amazon. Cool stuff. Best,Sergey

Hi, Im trying to solve an ODE equation system for an adiabatic closed reactor. When I try to solve via ODESOLVE all variables keep as straigth lines.Thanks in advance!

I have a matrix and i need to assign the first column as a second column in another matrix , can this be done without identifying each individual element? In the example above id like to be able to create matrix D without having to specify every element from matricies A and B . Hopefully with the output as per matrix C. Thanks ,  Ross 

to all, Attached is a 1st test of using mcad15 inverse Laplace. While I get something, is there a way of getting a “neater” response out of mcad15? For example mcad15 returns sqrt(wf^2) – why not wf ? I think one can end up getting imaginary numbers if one uses specific values ! I know some of the regular users are very handy at using Laplace operations so maybe I might get a few tips and/or tricks Thanks [correction: a square was missing!]

Hi everyone. I'm trying to plot 2 lines and a circle in mathcad prime 4, in the form (x-x0)^2+(y-y0)^2=R^2. I have values for x0 and y0 and R, but I can't figure out how to plot it. Solving for y gives me complex numbers. x0 and y0 are defined values of some earlier calculations, so their value can change, so they are not "fixed" numbers.   Any simple way to do this? (Seems all the info on this I can find is pretty old, and I can't open example files and such...)      

This thread was broken off of this original topic thread.     BTW, does anyone know, why Primes symbolic can't solve this simple system of equations? The new symbolic in Prime 6 claims that no solution was found and the legacy one (muPad) runs quite long and then we see A similar useless result in MC15 which uses MuPad, too. The system can be easily solved by hand and we get Guess MC11 with Maple under the hood for symbolic does not show that problem of not being able to solve this system.

I have only one Mathcad-sheet with ORIGIN not 0 or 1 See ORIGIN - PTC Community I have only one Mathcad-sheet with continue programming operator. I can show it! But we can creat this program without the continue operator. But with the continue operator it is nice, fine, прикольно! Do you have or do you seen a Mathcad-sheet with continue priogramming operator?

Hi all, I am trying to figure out if it is (mathematically) possible to obtain a x(y) function via the following system with odesolve: dx/dy=F(x) Do you guys have a idea if it is possible in mathcad, and if so, how?

Greetings, im trying to program something that fills a matrix automatically, but you can choose wich rows and columns to make 0 instead. So far i can do it by hand, just setting what row and colum i want (fil=row), and adding extra conditions to the "if"  I tried to use a matrix instead, like row:=[1 2 3], so if i= any of those 3 values, it assign it 0, but it doesnt seem to work with a matrix, i wrote it something like "if i=fil1_i" (_i meaning subscript), but it doesnt compare it to the value on the matrix. Im working with Power Flow equations, in this part i need to do a 2x2 matrix each space being a Jacobian matrix. Im trying to automate it, because this is with 2 "bars" so matrix are 2x2, but when its something like 6 bars i dont want to do everything by hand 

It will be very useful if you help me.
