Hi,
I want to write a shell script which increments a particular column in a row from a text file and then adds another row below the current row with the incremented value .
For Eg .
if the input file has a row :

I would like the script to create something like... (9 Replies)

Dear all,
Does anyone know how I could to add a column of numbers (1s, or 2s, or..., or 6s) to two-column text files (tab-delimited), where the specific number to be added varies as a function of the file naming?
Currently, each of my text files has two columns, so the column with the... (12 Replies)

Hello. Trying to add a column of numbers and combine the 1st and 2nd fields as uniq with the new total.
This works to add the numbers but can't figure an easy was to combine the 1st and 2nd column as the list is very long. awk '{s+=$3} END {print s}'

SGBEQU(l) ) SGBEQU(l)
NAME
SGBEQU - compute row and column scalings intended to equilibrate an M-by-N band matrix A and reduce its condition number
SYNOPSIS
SUBROUTINE SGBEQU( M, N, KL, KU, AB, LDAB, R, C, ROWCND, COLCND, AMAX, INFO )
INTEGER INFO, KL, KU, LDAB, M, N
REAL AMAX, COLCND, ROWCND
REAL AB( LDAB, * ), C( * ), R( * )
PURPOSE
SGBEQU computes row and column scalings intended to equilibrate an M-by-N band 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 ele-
ments 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.
KL (input) INTEGER
The number of subdiagonals within the band of A. KL >= 0.
KU (input) INTEGER
The number of superdiagonals within the band of A. KU >= 0.
AB (input) REAL array, dimension (LDAB,N)
The band matrix A, stored in rows 1 to KL+KU+1. The j-th column of A is stored in the j-th column of the array AB as follows:
AB(ku+1+i-j,j) = A(i,j) for max(1,j-ku)<=i<=min(m,j+kl).
LDAB (input) INTEGER
The leading dimension of the array AB. LDAB >= KL+KU+1.
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
