Row major order's implication on matrix vector multiplication. To perform multiplication of two matrices, we should make sure that the number of columns in the 1st matrix is equal to the rows in the 2nd matrix.therefore, the resulting matrix product will have a number of rows of the 1st matrix and a number of columns. Multiplying a matrix and a vector means creating a linear combination of the columns of the matrix with numbers from the vector as coefficients.
