Here is a slice of one of the data files.
So the cols are not really fixed width, there is no other delimiter other than a space. Not sure how cut would work if I want every 20th and 21st entry? Is there a way
@danmero, considering I have to read in a file to set i <=NF. I'm not sure how different your logic is to the original post other than the modification to print the first two columns? I guess I could also do it like:
The problem seems to be in the for loop, as different file lengths seem to return weird results, when for example the length of NF is different to 200?

Hi all,
What I want is that can we manage printing a text file on a Dot Matrix printer installed on a Linux machine and the printer should not take the normal A4 format, but should print only to the extent the text file has text in it. What happen usually is that when we give print comand to any... (0 Replies)
Hello,
I have a matrix 200*10,000 and I need to extract the columns between 40 and 77. I dont want to write in awk all the columns. eg: awk '{print $40, $41, $42,$43 ... $77}'. I think should exist a better way to do this. (10 Replies)
All,
I have a problem with grep/fgrep/egrep. Basically I am building a 200 times 200 correlation matrix. The entries of this matrix need to be retrieved from another very large matrix (~100G). I tried to use the grep/fgrep/egrep to locate each entry and put them into one file. It looks very... (1 Reply)
Hi Experts,
My requirement is to compare the second field/column in two files, if the second column is same in both the files then compare the first field. If the first is not matching then print the first and second fields of both the files.

Hello all,
I am quite new in this but I need some help to keep going with my analysis.
I am struggling with a short script to read a square matrix and convert it in two collumns.

The following code transform the matrix to columns. Is it possible to do it other way around ( get the input from the output) ?
input
y1 y2 y3 y4 y5
x1 0.3 0.5 2.3 3.1 5.1
x2 1.2 4.1 3.5 1.7 1.2
x3 3.1 2.1 1.0 4.1 2.1
x4 5.0 4.0 6.0 7.0 1.1

sorg2l
SORG2L(l) ) SORG2L(l)
NAME
SORG2L - generate an m by n real matrix Q with orthonormal columns,
SYNOPSIS
SUBROUTINE SORG2L( M, N, K, A, LDA, TAU, WORK, INFO )
INTEGER INFO, K, LDA, M, N
REAL A( LDA, * ), TAU( * ), WORK( * )
PURPOSE
SORG2L generates an m by n real matrix Q with orthonormal columns, which is defined as the last n columns of a product of k elementary
reflectors of order m
Q = H(k) . . . H(2)H(1)
as returned by SGEQLF.
ARGUMENTS
M (input) INTEGER
The number of rows of the matrix Q. M >= 0.
N (input) INTEGER
The number of columns of the matrix Q. M >= N >= 0.
K (input) INTEGER
The number of elementary reflectors whose product defines the matrix Q. N >= K >= 0.
A (input/output) REAL array, dimension (LDA,N)
On entry, the (n-k+i)-th column must contain the vector which defines the elementary reflector H(i), for i = 1,2,...,k, as returned
by SGEQLF in the last k columns of its array argument A. On exit, the m by n matrix Q.
LDA (input) INTEGER
The first dimension of the array A. LDA >= max(1,M).
TAU (input) REAL array, dimension (K)
TAU(i) must contain the scalar factor of the elementary reflector H(i), as returned by SGEQLF.
WORK (workspace) REAL array, dimension (N)
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument has an illegal value
