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

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

clag2z
clag2z.f(3) LAPACK clag2z.f(3)NAME
clag2z.f -
SYNOPSIS
Functions/Subroutines
subroutine clag2z (M, N, SA, LDSA, A, LDA, INFO)
CLAG2Z converts a complex single precision matrix to a complex double precision matrix.
Function/Subroutine Documentation
subroutine clag2z (integerM, integerN, complex, dimension( ldsa, * )SA, integerLDSA, complex*16, dimension( lda, * )A, integerLDA, integerINFO)
CLAG2Z converts a complex single precision matrix to a complex double precision matrix.
Purpose:
CLAG2Z converts a COMPLEX matrix, SA, to a COMPLEX*16 matrix, A.
Note that while it is possible to overflow while converting
from double to single, it is not possible to overflow when
converting from single to double.
This is an auxiliary routine so there is no argument checking.
Parameters:
M
M is INTEGER
The number of lines of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrix A. N >= 0.
SA
SA is COMPLEX array, dimension (LDSA,N)
On entry, the M-by-N coefficient matrix SA.
LDSA
LDSA is INTEGER
The leading dimension of the array SA. LDSA >= max(1,M).
A
A is COMPLEX*16 array, dimension (LDA,N)
On exit, the M-by-N coefficient matrix A.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
INFO
INFO is INTEGER
= 0: successful exit
