Plotting difficulty

Error message when plotting:

"These array elements must be scalars. They cannot be vectors or matrices."

How can this be fixed?

Using Mathcad Prime 10.0.1.0

In your plot, change rho (before max_proof) to sigma and it should work.

The rho is not defined, you defined sigma....

 

Success!

    Thank you, Luc - It was such a silly mistake on my part. Thanks for noticing it, and appreciate your feedback.

    Yo get a smoother plot if you define sigma as a function of "t" rather than a vector of a few values.
