(*) operator with a for loop is working for me.. Description. C = A.*B multiplies arrays A and B by multiplying corresponding **elements**. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each **element** of the other array.. The **element**-**wise** **matrix multiplication** of the given arrays is calculated in the following ways: A * B = 3. Scalar or Dot product of two given arrays The dot product of any two given matrices is basically their **matrix** product. The only difference is that in dot product we can have scalar values as well. A.B = a11*b11 + a12*b12 + a13*b13 Example #3.
