Vectorized exponentiation

Question

I have two vectors, X of bases and N of exponents. I want to get the matrix of all values e = xn for each x in

Answer 1

Use bsxfun:

bsxfun(@power, X, N)

This assumes that X is a column vector and N is a row vector. If you want to guarantee that, use the following syntax which is more robust:

bsxfun(@power, X(:), N(:).')
