WebbIt follows that one has also: r is the dimension of the row space of M, which represents the image of f*; m – r is the dimension of the left null space of M, which represents the kernel of f*; n – r is the dimension of the cokernel of f*. The two first assertions are also called the rank–nullity theorem . References [ edit] Strang, Gilbert. WebbThe rank-nullity theorem states that the dimension of the domain of a linear function is equal to the sum of the dimensions of its range (i.e., the set of values in the codomain that the function actually takes) and kernel (i.e., the set of values in the domain that are mapped to the zero vector in the codomain).
