Mathcad

To debug module (reference file) I need to have an area with input variables in the beginning of the module. I want to enable them in case of debuging and disable after. Is it possible? Does Prime have such possibility?

Hi, I know that MC15 doesn't like different units in one array and I know how to override this. But what to do in this case? I`m reading excel file to MathCAD and I want to get units from it. The unit in one "unit cell" can be "mm" or "deg".I don`t want to add one more column for "mm" or for "deg".I want to use one cell for different purposes. Is this possible? 

Hallo,   attached a mathcad file with my question. I need to call the function "on error" vectorised. So that i have a result of all the calculations I tryed it but the result is not correct. Can anyone help me with this problem?   As you can see the result is red because for the last value no calculation is possible. Therefor a fixed value should be calculated for the result. Or an "on error" function   Thx Stefan

Hi guys, I have a problem with an integral that I would like to link in the solve block using odesolve. The Integral (sin A(s) ds) can't be written in the solve block or the solution can't be found. I tried to rewrite the integral in a sum or I tried to use the trapezoidel rule, but it doesn't work either.   A(s) isn't given, but dA(s)/ds will be solved during the solution.   I am looking forward to your helpfull answers 😉   Best regards David      

Hi all! I'm currently using MathCad 15 and I can't seem to get the seem together the Excel function to work correctly. It keeps writing to excel and making the file corrupt and messing with the formating, making it impossible to write all the arrays to Excel is there something I'm doing wrong?

Do you know more interesting (not so simple) 3D-body plot? See please Mathcad 15 sheet in attach!

Hi,   I seem to be having a problem with my solve block at the end of my file. I know errors in solve blocks don't tell me much but any help would be appreciated.   Thanks!

Hi, I'm trying to assign a variable to the output of a solve block but there vector inputs and the output from the 'find' function is a series of 2x1 arrays, in one long array.  Sorry - it's hard to describe but an image is attached. I've created two blocks to show the problem - the last one showing the error when I want to assign the output to a variable. Thanks  

I'm currently working on an MathCad worksheet that will allow inputs be made into an Excel spreadsheet that way people that don't have MathCad can enter data for us to calculate answer using a template. My question is is there a way to put those answers found by MathCad back into the spreadsheet without deleting all it contents?

when it is launched, it always generates the following error message: failed to create empty document.  How to fix this?

I had a need to convert a small text file into a Mathcad 15.I need to transfer a text file a number like this:z23: = 0 + i * 0z24: = 1 + i * 0z25: = 1 + i * 0z26: = 1 + i * 0z27: = 0 - i * 1

Dear Experts, I want to find confidence intervals for estimated parameters using LeastSquaresFit. Without units, there is no problem. When using units, an error occurs if the fitting function defined as a program block. How to solve this problem? With units: Without units:  

This may seem trivial to most, but it frustrates me greatly.   In my line of work I frequently insert images into Mathcad sheets.  In Prime 3.1 the images would automatically resize themselves to be equal the width of the page.    Since our company installed Prime 4.0 I was devastated to see that this functionality had disappeared... now when you insert a large image it stretches off the page, requiring the user to open the Draft View, scroll across to the handles and then drag it down to size.   My question: is there a way to change this behaviour to be the same as in Prime 3.1 or am I stuck with this forever?

Hi everyone. I have a problem that i can't solve it, i need someone fix it for me.   I have to draw two graph in one coordinate system, but only the second graph is displayed. the first graph is not, i don't know why it's not displayed. i attach the zip files in post, this two graphs is on the page 20. Thank you very much ! 

I'm an engineer at NASA. We use a NIST Standard Reference Database (http://www.nist.gov/srd/nist23.cfm) called REFPROP to get the thermodynamic and transport properties needed to support our fluid calcs.The underlying code base in written in Fortran, but NIST provides several different methods for accessing the property data including:1) a stand-alone GUI2) an Excel Add-in3) instructions for adding wrapper code to create C-code compatible DLL'sI'm a long-time user of the Excel Add-in (and creating a DLL is beyong my programming level), but, given how units-intensive most of my calcs are, I was interested in seeing if Mathcad might be a viable alternative.I looked at Prime 2.0 last year, but based on how "crippled" it seemed to be relative to 15.0 I held off until Prime 3.0 came out.With the NIST-supplied REFPROP add-in loaded into my copy of Excel, I opened a Prime 3.0 worksheet, added an Excel component, and entered a REFPROP function call. At first it seemed to work, but later I noti

I'm trying to set up a solve block so I can call it as a function. In the this case it will find what cable size matches the manufacturers specifications and return the subscript for which it is at. But it keeps telling me that the variable is undefined. Can you explain what I'm doing wrong here?

First of all thank you for helping me. I am trying to figure out a way to use a if statement to compare to see if two variables are equal to each other?

hi everyone, i have a problem in drawing the graph, i don't know why it's wrong i want to draw the graph same as the second picture but as you see in the first picture, the graph has error. Here is the program i attach the zip file in post . Thank you so much !

result in Mathcad 15 M045 and in Mathcad Prime 4.0    

I've recently been using the Table feature as an easy way to list my input after seeing an exmaple posted here.  This spawned a few observations that may be of interest.     First, a one row table is a scalar and not a vector.  It's handy, but I've never seen it documented that this is an intended feature.       Next, I was entering data and tried to enter data as follows (a calculation).  I wasn't optimistic it would work, but it gives an answer for D_2.  It's the right value - but has changed units.    So, it appears that the unit in the table heading is simply multiplied by whatever is in the column.  Here's  how I get what I'm after (remove the column units).         I guess this was surprising as I expected D2 to be inches no matter what I entered.  And if the units didn't work out I expected an error.  But, D2 in fact comes through with whatever it calculates.

Help me please, I need to finish my course project!Why Given Minerr is not working? How can I combine two functions in one graphic?  

Hi, I have a problem with the given - find method. I have an error "This variable is undefined" and i don't know why. Any ideas? My mathcad version is 14.

If I have a vector 'k', with say 10 values in it.  I can easily do a sum of all the value using the summation operator with 'k' the ONLY argument.   If I want the product of all those values, it seems I need more arguments other than just 'k'.   Can anyone advise what those arguments should be?

The simple exation with one variable needs numerical solving( with higher potential values compute time climbes a bit), enabled multithreading - not much of a cpu hog ~ 50%(on an i5 2500) - yet no result in prime 4.0 Punched the same quation into WolframAlpha, got an approximated result - due to limited compute time.   Searched though the help tool of the solve function, tried different parameters, still nothing. Am I blind or missing something -  please enlighten me.(used the thick equation symbol)Thank you for wasting time on helping me 😉  

Hi,   When I'm trying to graph F(theta) an error tells me that the value must be a scalar and by error tracing, I found that in the first part of the if statement, the same error pops up. If anyone could help me out here that would be great.   Thanks
