how to apply a function to all rows in a matrix? [duplicate]

Question

Consider for example the function "norm". I have a matrix, and I want to apply "norm" to each row in the matrix, and get a vector of all norms for each row in this matrix.

I was hoping I could do norm(A, 'rows'), but that is not possible. Is there some other way to do it?

You can do it without converting to a cell array:

arrayfun(@(n) norm(A(n,:)), 1:size(A,1))
