my concern is how to delete the row !!!
i have a file which has a column that is unique

the above awk command which removes all the chars before and including '=' on the entire row. --thats what it meant be.:)
but i need to remove text on column-wise on each row.
many thanks,
EM

NOTE : If there is a pipe in the content... (6 Replies)

zlaqr1.f(3) LAPACK zlaqr1.f(3)NAME
zlaqr1.f -
SYNOPSIS
Functions/Subroutines
subroutine zlaqr1 (N, H, LDH, S1, S2, V)
ZLAQR1 sets a scalar multiple of the first column of the product of 2-by-2 or 3-by-3 matrix H and specified shifts.
Function/Subroutine Documentation
subroutine zlaqr1 (integerN, complex*16, dimension( ldh, * )H, integerLDH, complex*16S1, complex*16S2, complex*16, dimension( * )V)
ZLAQR1 sets a scalar multiple of the first column of the product of 2-by-2 or 3-by-3 matrix H and specified shifts.
Purpose:
Given a 2-by-2 or 3-by-3 matrix H, ZLAQR1 sets v to a
scalar multiple of the first column of the product
(*) K = (H - s1*I)*(H - s2*I)
scaling to avoid overflows and most underflows.
This is useful for starting double implicit shift bulges
in the QR algorithm.
Parameters:
N
N is integer
Order of the matrix H. N must be either 2 or 3.
H
H is COMPLEX*16 array of dimension (LDH,N)
The 2-by-2 or 3-by-3 matrix H in (*).
LDH
LDH is integer
The leading dimension of H as declared in
the calling procedure. LDH.GE.N
S1
S1 is COMPLEX*16
S2
S2 is COMPLEX*16
S1 and S2 are the shifts defining K in (*) above.
V
V is COMPLEX*16 array of dimension N
A scalar multiple of the first column of the
matrix K in (*).
