For loop iteration on each element of a matrix

I have a n-dimension matrix as the variables of an equation. I want to iterate the equation solution on each element of the variable matrix. I know about using (for 1:numel(matrix)) but I want to store the solutions of the equation on the (ith,jth) element locations in a matrix.
Thanks

Other alternative, remove completely the for-loop
x1 = [1 2 3 4;5 6 7 8;9 10 11 12;13 14 15 16];
x2 = [4 3 2 1;5 7 6 8;9 12 11 11;16 13 15 14];
f1 = 4*x1.^2-x2.^3+28;
f2 = 3*x1.^3+4*x2.^2-145;

Preallocate the output as the appropriate size. Then use linear indexing.
f1 = zeros(size(x1)) ;
