Script to sort data
Hi All,
I have a .csv file with 3 columns called nLats, nLongs, and fRes. in following format :
"nLats","nLongs","fRes"
0,0,-1
0,1,-1
0,2,-1
0,3,-1
0,4,-1
.........
.........
0,143,-1 nLats increments at nLongs=143
1,0, -1
1,1, -1
..........
..........
1,143,-1
2,0,-1
2,1,-1
.........
.........
2,143,-1
Goes till nLats = 71.
I wish to sort fRes value in nLats*nLons Array, ie an array of 72*144.
(nLats 1st) -1 -1 -1 -1 -1......................-1
.............................................
.............................................
.............................................
(nLats 72nd)-1 -1 -1 -1 -1.....................-1
the max value of nLats=71 starting from 0, ie 72 rows
the max value of nLongs=143 starting from 0, ie 144 columns.
How shall I proceed???
Thanks all,

claqge.f
claqge.f(3) LAPACK claqge.f(3)
NAME
claqge.f -
SYNOPSIS
Functions/Subroutines
subroutine claqge (M, N, A, LDA, R, C, ROWCND, COLCND, AMAX, EQUED)
CLAQGE
Function/Subroutine Documentation
subroutine claqge (integerM, integerN, complex, dimension( lda, * )A, integerLDA, real, dimension( * )R, real, dimension( * )C, realROWCND,
realCOLCND, realAMAX, characterEQUED)
CLAQGE
Purpose:
CLAQGE equilibrates a general M by N matrix A using the row and
column scaling factors in the vectors R and C.
Parameters:
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
A
A is COMPLEX array, dimension (LDA,N)
On entry, the M by N matrix A.
On exit, the equilibrated matrix. See EQUED for the form of
the equilibrated matrix.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(M,1).
R
R is REAL array, dimension (M)
The row scale factors for A.
C
C is REAL array, dimension (N)
The column scale factors for A.
ROWCND
ROWCND is REAL
Ratio of the smallest R(i) to the largest R(i).
COLCND
COLCND is REAL
Ratio of the smallest C(i) to the largest C(i).
AMAX
AMAX is REAL
Absolute value of largest matrix entry.
EQUED
EQUED is CHARACTER*1
Specifies the form of equilibration that was done.
= 'N': No equilibration
= 'R': Row equilibration, i.e., A has been premultiplied by
diag(R).
= 'C': Column equilibration, i.e., A has been postmultiplied
by diag(C).
= 'B': Both row and column equilibration, i.e., A has been
replaced by diag(R) * A * diag(C).
Internal Parameters:
THRESH is a threshold value used to decide if row or column scaling
should be done based on the ratio of the row or column scaling
factors. If ROWCND < THRESH, row scaling is done, and if
COLCND < THRESH, column scaling is done.
LARGE and SMALL are threshold values used to decide if row scaling
should be done based on the absolute size of the largest matrix
element. If AMAX > LARGE or AMAX < SMALL, row scaling is done.
