Gram–Schmidt process

Hello everybody,

I am trying to orthonormalize a basis using the Gram-Schmidt process. Is it possible with FreeFem ++?

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.
