NAME

cgerc.f -  

SYNOPSIS


 

Functions/Subroutines


subroutine CGERC (M, N, ALPHA, X, INCX, Y, INCY, A, LDA)
CGERC  

Function Documentation

 

subroutine CGERC (INTEGERM, INTEGERN, COMPLEXALPHA, COMPLEX,dimension(*)X, INTEGERINCX, COMPLEX,dimension(*)Y, INTEGERINCY, COMPLEX,dimension(lda,*)A, INTEGERLDA)

CGERC Purpose:

 CGERC  performs the rank 1 operation    A := alpha*x*y**H + A, where alpha is a scalar, x is an m element vector, y is an n element vector and A is an m by n matrix. 


 

Parameters:

M

          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           On entry, ALPHA specifies the scalar alpha. 


X

          X is COMPLEX 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 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 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 ).
