Hi,
I'm trying to convert some old Mathcad files into SMath but am stuck with what must be an elementary problem, I've looked at various tutorials but can't find a solution, no doubt due to my own incompetence.

I am defining the following variables: angle:=72 and varangle:= 0, angle/2..360

In Mathcad if I then define: test(varangle):= cos(varangle) the output of test(varangle) displays correctly in a column.

If I try the same in SMath I receive either an 'argument must be scalar' or 'fill in all empty elements' error.

Thanks for any advice.

Screenshots of Mathcad and SMath attached.

btw, great software.

Correct me if i'm wrong, trigonometric functions don't support arrays currently.
For now, you can do something like this.

Thank you kilele

You can convert the vector into a system (by w3b5urf3r_reloaded)

did arrays appear in trigonometric functions?

now you can use the "vectorize" function, which you also find in the side panel, and perform the trigonometric function element by element.

An alternative to the vectorize() function is the use of index vectors.

They, however, only work if they are used in a definition.
