C = A .* B "dot-multiply" works element by element (Hadamard multiplication). > 2) How to generate square values of the elements in matrix C to get > matrix D : > > For example, matrix C (3x3): matrix D > (3x3): > 4 2 6 > 16 4 36 > 2 0 2 > 4 0 4 > -3 2 4 > 9 4 16 D = C .^ 2 "dot-raise to power" also works element-wise.
