Learn more about row vector, multiply, matrix, scalar trying to multiply the third row of a matrix by another row, B: A = data(3, ;).*B where B is a row vector Need help finding a way to multiply the 3rd row of my matrix by a scalar value, for exam... WebMultiplication of a matrix by a scalar is also defined elementwise, just as for vectors. Create a 3 by 2 matrix A, the calculate B = -2A and C = 2A + B. A is a 3 by 2 matrix. B is a 3 by 2 matrix with each element equal to -2 times the corresponding element of A. The result C is the 3 by 2 matrix with each element equal to 0. >> A = [1 2; 3 4; 5 6]
