Dear Unix Gurus,
I have a sample data set that looks like this
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
I want to open it up so that I get
x1 y1 0.3
x2 y1 1.2
x3 y1 3.1
x4 y1 5.0
x1 y2 0.5
x2 y2... (3 Replies)
I have a huge matrix file containing some 1.5 million rows and 6000 columns. The matrix looks something like this:
1 2 3
4 5 6
7 8 9
3 4 5
I want to add all the numbers in the columns of this matrix and display the result to my stdout. This means that the numbers in the first column are:

Hi All,
I have a huge (and its really huge!) matrix about 400GB in size (2 million rows by 1.5 million columns) . I am trying to optimize its space by creating a sparse representation of it.
Miniature version of the matrix looks like this (matrix.mtx):
3.4543 65.7876 54.564

Hello to all,
I am very new in the shell scripting and I need help. I have data for several individuals in several rows followed by a tag and by 5 values per row, with the name of the individual in the first column, e.g.:
IND1 H1 12 13 12 15 14
IND2 H2 12 12 15 14 14
IND3 H1 12 15... (2 Replies)
Hi guys,

Hi Friends,
I have an input matrix file like this
Col1 Col2 Col3 Col4
R1 1 2 3 4
R2 4 5 6 7
R3 5 6 7 8
I would like to consider only the numeric values without touching the column header and the row header.
I looked up on the forum's search, and I found this. But, I donno how to... (3 Replies)
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.

CUNG2R(l) ) CUNG2R(l)
NAME
CUNG2R - generate an m by n complex matrix Q with orthonormal columns,
SYNOPSIS
SUBROUTINE CUNG2R( M, N, K, A, LDA, TAU, WORK, INFO )
INTEGER INFO, K, LDA, M, N
COMPLEX A( LDA, * ), TAU( * ), WORK( * )
PURPOSE
CUNG2R generates an m by n complex matrix Q with orthonormal columns, which is defined as the first n columns of a product of k elementary
reflectors of order m
Q = H(1)H(2) . . . H(k)
as returned by CGEQRF.
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) COMPLEX array, dimension (LDA,N)
On entry, the i-th column must contain the vector which defines the elementary reflector H(i), for i = 1,2,...,k, as returned by
CGEQRF in the first 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) COMPLEX array, dimension (K)
TAU(i) must contain the scalar factor of the elementary reflector H(i), as returned by CGEQRF.
WORK (workspace) COMPLEX array, dimension (N)
INFO (output) INTEGER
= 0: successful exit
< 0: if INFO = -i, the i-th argument has an illegal value
