ok, I understand, but when I write vectorization, there is no such component, most likely there is simply no plugin or am I mistaken?

Please just update your SMath.
Older versions lack a lot of useful features.
They also may have some serious calculation errors.
Don't forget to update your plugins after.

BTW vectorize() is available in stable releases since SS 0.98.5935 (April 2016)

Confirmed ... before that update, we used number of adapted codes.
SS 6179 is then updated, working perfect as designed.
