MATLAB: Apply a function to every element of a square matrix

Question

I have a square matrix and I would apply a function to every element of that matrix in the way I get a new square matrix where every element is the result of the function.does it exist a function for the purpose?

Answer 1

Yes, arrayfun()

For example:

    x = randn(10,10)+1i*randn(10,10);
    y = arrayfun(@conj,x);

or

      x = randn(10,10);
      y = arrayfun(@(x) x.^2,x);
