Matrice injective
WebIf it has full rank, the matrix is injective and surjective (and thus bijective ). You could check this by calculating the determinant: Hence the matrix is not injective/surjective. If the … Web(b) fest injective : si f(M) = O, cela donne MA= O. On multiplie cette égalité par Bà droite : MAB= OB ou encore M= MI= O: (c)Par le théorème 3, fest donc aussi surjective. (d)Alors …
