There are tow types of matrix multiplication : scalar-by-matrix multiplication and matrix-by-matrix multiplication. As a noun, a scalar is a single number or scale factor that all the matrix elements are multiplied by in scalar multiplication. This is used to scale down all the elements of a matrix in equal proportion. In graphics, this is used on row and column vectors that represent points in space. It moves a point radially toward or away from the origin(0, 0, 0). This is often done to put the values of x, y, and z within a range that graphics routines can more easily handle, especially when integer arithmetic is being performed. 1, record 1, English, - scalar%2Dby%2Dmatrix%20multiplication

matrix-by-matrix multiplication is a sum-of-the-products operation. The result is a matrix. The multiplier, multiplicand, and product matrixes may all be of different dimensions, but their dimensions must match(in a certain way). This matching corresponds to the way the sums of products are generated from the two matries... 1, record 2, English, - matrix%2Dby%2Dmatrix%20multiplication
