Hi,
I want to print column value based on row number say multiple of 8.
Input file:
line 1 67 34
line 2 45 57
. . .

Is it possible to print max number of 2 columns - awk
note: print max if the integer is positive and print min if the integer is negative
input
a 1 2
b 3 4
c 5 1
d -3 -5
d -5 -3
output
a 2
b 4
c 5
d -5
d -5 (4 Replies)
Hi.
How can we print those rows of file2 which are mentioned in file1. first character of file1 is a row number.. for eg
file1
1:abc
3:ghi
6:pqr
file2
a abc
b def
c ghi
d jkl
e mno
f pqr

Hello Team,
Need your expertise on following:
Here is the set of data:
C1|4|C1SP1|A1|C1BP1|T1
C1|4|C1SP2|A1|C1BP2|T2
C2|3|C2SP1|A2|C2BP1|T2
C3|3|C3SP1|A3|C3BP1|T2
C2|2|C2SP2|A2|C2BP2|T1
I need to filter above date base on following two steps:
1. Group them by column 1 and 4

SGEEQU(l) ) SGEEQU(l)
NAME
SGEEQU - compute row and column scalings intended to equilibrate an M-by-N matrix A and reduce its condition number
SYNOPSIS
SUBROUTINE SGEEQU( M, N, A, LDA, R, C, ROWCND, COLCND, AMAX, INFO )
INTEGER INFO, LDA, M, N
REAL AMAX, COLCND, ROWCND
REAL A( LDA, * ), C( * ), R( * )
PURPOSE
SGEEQU computes row and column scalings intended to equilibrate an M-by-N matrix A and reduce its condition number. R returns the row scale
factors and C the column scale factors, chosen to try to make the largest element in each row and column of the matrix B with elements
B(i,j)=R(i)*A(i,j)*C(j) have absolute value 1.
R(i) and C(j) are restricted to be between SMLNUM = smallest safe number and BIGNUM = largest safe number. Use of these scaling factors is
not guaranteed to reduce the condition number of A but works well in practice.
ARGUMENTS
M (input) INTEGER
The number of rows of the matrix A. M >= 0.
N (input) INTEGER
The number of columns of the matrix A. N >= 0.
A (input) REAL array, dimension (LDA,N)
The M-by-N matrix whose equilibration factors are to be computed.
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
R (output) REAL array, dimension (M)
If INFO = 0 or INFO > M, R contains the row scale factors for A.
C (output) REAL array, dimension (N)
If INFO = 0, C contains the column scale factors for A.
ROWCND (output) REAL
If INFO = 0 or INFO > M, ROWCND contains the ratio of the smallest R(i) to the largest R(i). If ROWCND >= 0.1 and AMAX is neither
too large nor too small, it is not worth scaling by R.
COLCND (output) REAL
If INFO = 0, COLCND contains the ratio of the smallest C(i) to the largest C(i). If COLCND >= 0.1, it is not worth scaling by C.
AMAX (output) REAL
Absolute value of largest matrix element. If AMAX is very close to overflow or very close to underflow, the matrix should be
scaled.
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument had an illegal value
> 0: if INFO = i, and i is
<= M: the i-th row of A is exactly zero
> M: the (i-M)-th column of A is exactly zero
