custom CreateMesh function of vector argument

[ifomenko]

I`m trying to create function CreateMesh.f which works with vector argument but I met some problems

EDIT: I found the way, but I don`t understand why the first one doesn`t work

Mathcad/muPad does not know that your {x} should be a two-element vector unless you provide a two-element vector (x,y) instead of a single variable name. Thats why your first attempt fails and the second succeeds.

Furthermore "CreateMesh" is a numeric command only - its not known by the symbolic processor.

Your second approach does not use symbolics and to me its much more clearer and straight forward anyway. I would prefer it even if the first one would work 😉

BTW, here is a modification of your first approach using symbolics, but as already written, I still would prefer your second approach.

Many thanks, I understood

Here is an even shorter variant of your second approach:
