 Scaling a matrix with a scaler:

Imagine you have a magic multiplier device, represented by the scalar k. This tool can stretch or shrink any matrix you give it. Let's see how it works on a simple 2x2 matrix:

A = [A  B]

       [C  D]

Here, A, B, C and D are different elements of the matrix. To scale this matrix with k, we simply multiply each element by k:

K * A = [ K*A  K*B ]

          [k*c  k*d]

As you can see, each element in the original matrix A is now multiplied by k. This means that the entire matrix stretches or shrinks proportionally, depending on whether k is greater or less than 1.
