How to trace the curve on plot. I would like to generate the plot from data which is in my excel sheet 

Hello, Everyone.From : Thanks in advance for your time and help.Best Regards.Loi

Hi allI am using Visual Basic for Application in Excel and am trying to pass an array of strings from Excel to Prime 8 through the API. I have managed to pass a matrix/array of numbers, but if I change the matrix content to strings, the OutputGetMatrixValue object fails with Errorcode = 7, suggesting "Matrix result is invalid." See Figure.png and below code. It appears not possible from the help documentation, see Figure2.png. Alternatively, I could convert the strings to unicode numbers, and then pass them to Excel through the below code, and then convert them back to strings. Or use a text file? Any suggestions for the easiest way forward? 'Get a matrix valueSet out2 = ws.OutputGetMatrixValue("out2")Dim q As VariantRowCount = out2.MatrixResult.RowscolCount = out2.MatrixResult.ColumnsReDim q(RowCount - 1, colCount - 1)For i = 0 To RowCount - 1For j = 0 To colCount - 1d = out2.MatrixResult.GetMatrixElement(i, j, dblhere)q(i, j) = dblhereDebug.Print "q(" & i & ","

I am in the process of writing an M050 worksheet, a patent disclosure, into Prime8. Quotient numerator and denominator are usually power series in root(s). In M050, simplify gives me a quotient in integral power of the complex variable, (s). Nothing seems to work in Prime8. This is so basic; it is a nuisance. I must be doing something wrong.

Does anyone know how to turn off the green outline that appears around duplicate variables in Prime 8.0? It even occurs around subsequent members of an array, which are technically not the same variable. Please see the attached screen shot. The green outline didn't exist in Prime 7.0 but suddenly showed up in Prime 8.0. I would like to get rid of it since it doesn't appear very professional in a printout. 

HI i dont know who i cant convert the file from xmcd to mcdx. can some kind soul help me to convert it ?

Hello do anyone have a work around for the following problem, i am trying to multiply the terms within Tidx by Phi and b, of which i get the correct result (when undefined). when i try to define that to put into another equation it pull through an error.   Sheet attached thank you 

How do I get the lbf-ft units always when evaluating the equation. I need to enter it manually  always  I am using USCS unit system should I change it?

Hi everyoneIs it possible to install (permanently) E-books (like for example one of my favorites "dynamassist" or "Images") in a directory different from the /Handbook directory, where I have no write rights?I have seen, I can open an E-book wherever I want, but the ones stored in /Handbook remain available also after closing and starting MathCAD again.  Thanks a lot!Best regardsClaudio

Hi guys i am having a error when trying to find a Phi value between two types; essentially if Srtype is "cohesive" for that layer of ground then Phi should be = to 0 deg. Else read from the value from the table for the following increments and so on...... sheet is attached,  thank you and help would be appreciated  

Hello, I am trying to solve a system of differential equations to calculate the change of temperature and pressure in switchgear during an arc fault. The equations are as follows:where C2 equals: "T" is temperature and "p" is the pressure, PL is the power of the arc which is a function of time and is calculated earlier. The rest are constants.I've attemped to calculate this in Mathcad Prime 8 using the rkfixed function, inputting the full equations with the C2 factored into the them:I've input "T" as "y0" and "p" as "y1" in the equations using the matrix index operator. The first equation if for temperature and the second for pressure. The initial conditions are for the initial temperature of 300 and pressure of 101325. I'm getting an unknown error which roughly translates to "calling object expection". It does seem to dissapear when i replace one of the "y0" or "y1" variables with a constant in the second equation, but not in the first. However the results are then inco

Where does the server/daemon information get added on a Mathcad/PTC license file ?I'm getting an error 1067, and my log says:  License manager can't initialize. No server lines in license file.

I'm looking for a way to convert this from .xmcd to .mcdx, but I can no longer download Mathcad 15. What can I do?

I'm developing a MathCAD worksheet in Prime7 that works with data extracted from input matrices.  I cannot figure out how to take two variables, each of which comprise a 12 row x 1 col matrix, and compare each pair of values row by row to find the Maximum value, then spit that row's maximum value out into a new resulting column matrix. My last attempt at a programming block with a simple concept is at the end of the worksheet, but instead of producing a column matrix only goes straight to the last iteration value and reports it. Worksheet attached...thanks for any help!

Hello,  I tried to calculate the  price in euros but unfortunately I am not able to view it in Euros. I could view it view it only in the form the declared currency. How can I resolve it

Somehow I am not getting the function to work in 15. Can someone help on this. 

When I converted a trial version of 8.0 to a licensed version, the legacy converter was not enabled, and this means 20 years of Mathcad 2001i Professional programs are not available.  There is a drop-down menu comment that 'setup' should be run again to enable the legacy conversion option.  I see no 'setup.exe' anywhere in the 8.0 files.  Does this mean that you have to download a new version of Mathcad 8.0?  Why is this not a default load since it is one of the dropdown menu options?  

Hi Everyone,  In my MATHCAD Solveblock, I have four implicit equations, with four independent variables, whereby I need to find a solution to those variables.  The four independent variables are as follows:  1. Angle, β  2. Angle, Φ 3. Length, a  4, Length, b  In addition to that I have a couple of constraints for these values as well.  The PROBLEM that I am facing currently is the fact that the 4 variables above do not converge to single final values, as it is highly dependent on the guess values that I initially enter into the SolveBlock. In other words, if I change any one of the guess values for any of the 4 variables, the final value for the variables are change drastically.  I have attached my file in this post for review. Hoping someone could help me with this!

Can anyone help with a problem I'm having with with a Given function inside a loop as shown below:The function Fopt is defined previously. The steps work correctly one at time when f1 is not an indexed function but it won't work as shown. Any suggestions? 

It seems that I have a corrupted mathcad file. I get the following error message when I try to open it. I am using version 15. Is there a way to fix this, I've attached the file.

I'm having trouble returning an array for a term in an equation. I have a spreadsheet that should generate a P-M diagram for a column. It correctly calculates the array of P values, The spreadsheet will return an array of M values, but they are incorrect. When picking the equation for M apart bit by bit, I have found that one term returns a scalar value rather than an array. Preceding calculations for this term correctly return arrays, but this one does not. The term in question in the attached file is c*((ri^2) - y^2). Even when I rewrite the variable c in terms of y, it still returns the same single number. For reference, when y= -11.5, the correct value should be 0, and when y= -11.25, the correct value for the term above should be 18.876 in^3. What am I doing incorrectly? 

A simple equation solved symbolically for an unknown variable returns two results, - as expected.However I know the result lies in the range 0 - 1.If I add an 'assume' modifier to limit the result to the value <1, I get quite an unexpected result.The units are obviously causing all sorts of mayhem.What's going on here?

I do not understand why the result being returned is a vector.  I am passing a value for both R and Y

I am not getting why this is evaluating in such a way in Mathcad 15

As per the original post..   Andy, my situation is similar to Jamie’s. I bought a single perpetual license (at least that is what I thought I purchased) many years ago and therfore I have no SCN or an SON number, only the product key. Now I have a new computer and due to the current situation I can’t get a new license file. Can you forward me to the customer/technical support, so that my mathcad 15 license will be transferred to my new computer.   Michael
