SpletThe nullity of a matrix is the defined as the dimension of it’s kernel. To find this, we usually apply “ERO”s (short for elementary row operations). The idea is that given some matrix A, if we multiply A by an invertible matrix E on the left side, than it’s kernel will remain the same. This is because for all x in .
