CLA_LIN_BERLAPACK routine (version 3.2)CLA_LIN_BERR(1)NAME
CLA_LIN_BERR - CLA_LIN_BERR compute component-wise relative backward
error from the formula max(i) ( abs(R(i)) / ( abs(op(A_s))*abs(Y) +
abs(B_s) )(i) ) where abs(Z) is the component-wise absolute value of
the matrix or vector Z
SYNOPSIS
SUBROUTINE CLA_LIN_BERR ( N, NZ, NRHS, RES, AYB, BERR )
IMPLICIT NONE
INTEGER N, NZ, NRHS
REAL AYB( N, NRHS ), BERR( NRHS )
COMPLEX RES( N, NRHS )
PURPOSE
CLA_LIN_BERR computes component-wise relative backward error from
the formula
max(i) ( abs(R(i)) / ( abs(op(A_s))*abs(Y) + abs(B_s) )(i) )
where abs(Z) is the component-wise absolute value of the matrix
or vector Z.
