`zgetri:`procedureThese routines compute the inverse of a matrix using the LU factorization computed by the xGETRF routines. Argument

*A*must contain the factors L and U from the LU factorization computed by xGETRF. Argument*PIVOT*must be the pivot vector returned by the factorization routine. Optional argument*LDA*is the leading dimension of array*A*. The return value is the inverse of the original matrix*A*.
