For example, if one of a or b is a scalar, then the scalar is combined with each element of the other array. This matlab function is the matrix product of a and b. The vector is treated as though it is a matrix of the same size as a, so that each element in the vector is added to a row in a. Pdf support dintroduction a matlab et simulink cours.
