M is INTEGER On entry, M specifies the number of rows of the matrix A. M must be at least zero.N N is INTEGER On entry, N specifies the number of columns of the matrix A. N must be at least zero.ALPHA ALPHA is COMPLEX*16 On entry, ALPHA specifies the scalar alpha.X X is COMPLEX*16 array of dimension at least ( 1 + ( m  1 )*abs( INCX ) ). Before entry, the incremented array X must contain the m element vector x.INCX INCX is INTEGER On entry, INCX specifies the increment for the elements of X. INCX must not be zero.Y Y is COMPLEX*16 array of dimension at least ( 1 + ( n  1 )*abs( INCY ) ). Before entry, the incremented array Y must contain the n element vector y.INCY INCY is INTEGER On entry, INCY specifies the increment for the elements of Y. INCY must not be zero.A A is COMPLEX*16 array of DIMENSION ( LDA, n ). Before entry, the leading m by n part of the array A must contain the matrix of coefficients. On exit, A is overwritten by the updated matrix.LDA LDA is INTEGER On entry, LDA specifies the first dimension of A as declared in the calling (sub) program. LDA must be at least max( 1, m ).
