Hello,
Would you please let me know if we can define a function with sub or superscript.
Something like: Usub"Tip"(x,y)=-----
Thanks,

How can I safely distribute Mathcad worksheets on our company
Our company has developed several mathcad worksheets and each new employee improve their own version of each worksheet but they do not shared this with anyone and when he is fired he takes all this knowledge and hard work.
Its there any solution for this problem.
Best Regards from Chile

Memory problems stacking Matrices
I have a small programm trying to split a matrix depending on the content in the rows. Now I'm using the folling algorithm:
take the row as submatrix on the actual position
stack that on one of the two alternative matrizes depending on a condition
Unfortunately this has a very poor performance both time and memory wise.
Assigning the rows via i,j to a new matrix seems to be better. Any ideas why?
thanks

Exponential Fit Curve Help
Hello,
I am trying to create a best-fit curve for a data set. I have imported two excelsheets containg the data into Mathcad. Each excel contains 1066 intergers. I have plotted them using the x-yplot functionality. The plot appears to follow an exponential projection. So, I tried to obtain exponential fit curve using the expfit() function. However, the fit function that I obtained is not correct, because it does not fit the data.
Please advise what I shoulddo to obtain the proper exponential fit curve.

Odesolve Block
Hello,
Please look at the attached worksheet. At the bottom of the sheet, Y:=Odesolve(x,20) is red and says " No "Given" found to open this solve block."
I have "Given" before my DE. Would you please locate the problem and help me to resolve this issue?
Thank you so much for your time and help.

How to extract a symbolic only function to the numeric processor
Some functions are only recognized by the symbolic processor. I am looking for a way to encapsulate some of these functions so they are available to the numeric processor via a normal function call. An example with one such function - Si(x) - is shown in the attachments, with various schemes I have tried. The element-by-element approach in item 2 works for assigning values to an array of arguments, but is a bit more awkward than I prefer. My attempts at defining a function in items 4-6 haven't worked.
Is there a way to define a function that is recognized by the numeric processor that does effectively what is in item 4, but works? If it can be done for a scalar, then I would assume that vectorizing this function would allow evaluation with array arguments, since the symbolic encapsulation is isolated in the scalar function definition.
If responding with a file, please save in mcd11 format.
Thanks,

Pop-up window
In my calculations at a certain time occurs a pop-up window with a specific question:
Is it possible to create a pop-up window like the following type (answer "Yes" must return "1" and "No" return "0" into variable "Question")?

How to insert plot from another sheet?
Hello,
I am using a plot very often. The problem is that this plot is time consuming to create and it would be nice if I could import it from another sheet.
Copy and paste doesn't work. Any alternative?

GRAPH plotting using generated data
Hello,
I have a worksheet (attached), with generated DeltaQ values.
I would like to plot graphs as depicted bellow:
Could anyone please help me to obtain these plots?
Please note: change rho and x0 globally at the bottom of the worksheet to get the corresponding values of DeltaQ.
Thank you,

Import from MathCad to WORD
Hell everybody,
Please look at the attached worksheet. I try to copy and paste one graph into WORD.
After doing this and also UNGROUPING the figure for further editing, curves will expand beyond the graph frame (border).
If the curves expand in one direction only, then I could use "if" command to restrict the output. In this case as you can see bellow, the curves expand on two directions. I tried to use "if" and "and" command but couldn't.
Would you please help me to solve the issue?
Thanks for the time.

AUTOMATED (PROGRAMMED) CALCULATIONS
Hello everybody,
I have attached a MathCad 15 worksheet. I would like to make tables of the following parameters for 3 values of alpha and for different rhos.
rho values: 2, 5, 10, 20, 30, 50 and 60
x1c, x2c and x3c corresponding to alpha=0.50, 0.45 and 0.40 respectively.
Q1c, Q2c and Q3c - same thing.
y1c, y2c and y3c - same thing.
Please go to the "Xc, Qc and Yc Section" on the worksheet.
Also, I would like to make some graphs of these parameters.
Thank you so much for the time and help.

PS final results as an array would be OK. I guess, it can then be exported to excel. OR, can MactCad produce tables?

Possibilities of Tabes in Mathcad - in Comparisson with Excel
Dear Mathcad users,
I´m looking to create a datatable and plot in Mathcad.
The data in the table are dependent on two variables, independent of each other. The extreme values of the endresult are calculated seperately but schould be a part of the final plot. Is this possible, and is it possible in an unlizenzed Mathcad?
The Excel sheet and my Mathcad-try are attached to this post. In the Excel-Table, the first two colums are the variables, all the following columns depend on them. The pink cells are the extreme values.
I also have a few other questions:
1) The mathcad I have installed is Prime 2.0. It saves teh data with a mcdx extension. I can not open mcd extensions created in a previous version of mathcad. Is my data lost?
2) Is it possible to crate pdf outputs from mathcad?
3) Is it possible to create a sheet format with frame, logo, etc, etc....?
Best regards from a real newby

This array index is invalid for this array

I am trying to replicate a relatively simple worksheet from:

I get the above mentioned error when typing the infromation about sectorial coordinates on the page 2. I have also attached the worksheet. How come it works for the author of the document but not for me? Is it because it is another version of MathCAD? If so how can I fix it?

functions within functions
I am wondering how one uses a function within a function. For exampe:
t=0,1..10
f(t):=2*t
then t and f(t) are vectors of length 10. t contains the 11 numbers 0-10 and f(t) contains the 11 numbers 0 through 20
Now, I need to use the values of f(t) in another equation, like:
g(f(t)):=10*f(t)
I should be able to get a vector of 11 numbers ranging from 0 to 200, but I can not make this work.
In my actual problem I am using an ODE solver to get the values f(t) and so I can't just change the algebra. I need to use the values of f(t) in another equation? HOW DO I DO THIS
