4 Matrices

Notice there are two types of multiplication Scalar multiplication refers to the product of a matrix times a scalar (real number) A scalar may be multiplied by a matrix of any size On the other hand, matrix multiplication refers to taking the product of two matrices The de nition of matrix multiplication may not seem very natural at rst

Matrix Subtraction and Scalar Multiplication You can use either of these methods to subtract (element by element) or multiply (all elements by the same value) For example: {=6*A} would produce a new array with all values in A multipled by 6 Multiplying Two Matrices Matrix multiplication requires that the two matrices are “conformable” (that

TS2 Chapitre 2 – Calcul matriciel I – Matrices : exemple et

La multiplication matricielle n'est pas commutative → la matrice notée A– 1 vérifiant A× –1=I est appelée l'inverse de A • La matrice notée I, constituée de 1 sur la diagonale et de 0 partout ailleurs, est appelée matrice unité C'est
