Question

Using a user-defined variable in a program block in MathCad Prime 11

I define a vector variable X (using a program block) in one part of the MathCad document.

The variable is computed correctly and I can access any element Xi later on by the expression Xi :=

However when I try to call Xi inside another program block further down, I get "This variable is undefined" error.

Would appreciate any suggestions.

Please attach your worksheet file and state which version of Mathcad you are using.

 

Success!

What you describe should work, given that you use ranges or for-loops the correct  way and use the correct type of index.

See simple example below.

We would have to see your worksheet to be able to find what you did wrong.
