**Thank you.**

Yes, just do `for`

loops with vectors of vectors `real[int][int]`

or `complex[int][int]`

.

Thank you very much for you response.

But, I hope to use a pre-programmed function in Freefem ++ if it exists.

It doesn’t exist. Why would you need that?

Well, since there is no function in FreeFem ++ I will try to program it.

I need it to orthonormalize a matrix where the columns are the elements of a basis.
