Hello everyone,
I am trying to plot a function that has two different variables: theta and phi.
Theta = -pi/2:0.1:pi/2
Phi = Specific Values at 0 and pi/2
I have an error that says:
"Error: Data must be numeric, datetime, duration, categorical, or an array convertible to double."
I’ve tried looking up this error on different discussions. However, I wasn’t able to find anything that helped with my specific scenario.
I have tried different methods and approaches: Using "symbolic variables", fimplicit function, fplot function, etc. However, I got different errors everytime I tried a different approach.

I attached my code for reference:
