Hye all,
I would like some help with reading in a file in which the data is seperated by commas. for instance:
input.dat:
1,2,34,/test
for the above case, the fn. will store the values into an array -> data as follows:
data = 1
data = 2
data = 34
data = /test

Ok; here is the code
INCREMENT=0 #Final Count
MATCH=0 #Treated as a Boolean
declare -a LINEFOUR #Declared Array
for FILE in $DIR; do # DIR was declared earlier
test -f $FILE && (
TEMP=(sed -n '4p' $FILE) #How do I assign the fourth line of the file to TEMP? This doesn't... (1 Reply)

I want to read only one column in "|" delimited file and write that column to a new file.
For Ex:
Input File
1|abc|324|tt
2|efd|11|cbcb
3||1|fg
4|ert|23|88
Output : I want to read column 3 in diff file.
324
11
1
88
Can anyone give me inputs on this ? (2 Replies)
Hi -
I have a file that contains data in this format:-
#comment
value1 value2 value3
#comment
value4 value5 value6 value7
#comment
value8 value9
I need to read value1, value2 and value3 into one array, value4 value5 value6 and value7 into another array and value8 and value9 into a 3rd... (2 Replies)
hi all, i have a data file that contains 2 columns, names and numbers. i need to read names in to a an array call names and numbers in to an array call numbers. i also have # and blank lines in my dat file and i need to skip those when i read the dat file. how do i do this? btw, my column 1 and...

Ok so I am new to perl and I am trying to write a random .cpt file for a GMT script for a class. Anyways I successfully read in the columns out of the file I wanted and I was able to generate 3 arrays full of random numbers that were the same length as the columns and now I just need to output them...

Hi fellas,
I have two files such as:
File 1
interacao,AspAsp,AspCys,CysAsp,CysCys,classe
File 2
interacao,AspAsp,CysAsp,AspCys,CysCys,classe
beta_alfa, DA, CA, DD, CD,ppi
Thus, I want to make a File 3 using the File 1 as model:
e.g.

Hi, I'm trying to use awk arrays to compare values across two files based on multiple columns. I've attempted to load file 2 into an array and compare with values in file 1, but success has been absent. If anyone has any suggestions (and I'm not even sure if my script so far is on the right lines)... (4 Replies)

CLABRD(l) ) CLABRD(l)
NAME
CLABRD - reduce the first NB rows and columns of a complex general m by n matrix A to upper or lower real bidiagonal form by a unitary
transformation Q' * A * P, and returns the matrices X and Y which are needed to apply the transformation to the unreduced part of A
SYNOPSIS
SUBROUTINE CLABRD( M, N, NB, A, LDA, D, E, TAUQ, TAUP, X, LDX, Y, LDY )
INTEGER LDA, LDX, LDY, M, N, NB
REAL D( * ), E( * )
COMPLEX A( LDA, * ), TAUP( * ), TAUQ( * ), X( LDX, * ), Y( LDY, * )
PURPOSE
CLABRD reduces the first NB rows and columns of a complex general m by n matrix A to upper or lower real bidiagonal form by a unitary
transformation Q' * A * P, and returns the matrices X and Y which are needed to apply the transformation to the unreduced part of A. If m
>= n, A is reduced to upper bidiagonal form; if m < n, to lower bidiagonal form.
This is an auxiliary routine called by CGEBRD
ARGUMENTS
M (input) INTEGER
The number of rows in the matrix A.
N (input) INTEGER
The number of columns in the matrix A.
NB (input) INTEGER
The number of leading rows and columns of A to be reduced.
A (input/output) COMPLEX array, dimension (LDA,N)
On entry, the m by n general matrix to be reduced. On exit, the first NB rows and columns of the matrix are overwritten; the rest
of the array is unchanged. If m >= n, elements on and below the diagonal in the first NB columns, with the array TAUQ, represent
the unitary matrix Q as a product of elementary reflectors; and elements above the diagonal in the first NB rows, with the array
TAUP, represent the unitary matrix P as a product of elementary reflectors. If m < n, elements below the diagonal in the first NB
columns, with the array TAUQ, represent the unitary matrix Q as a product of elementary reflectors, and elements on and above the
diagonal in the first NB rows, with the array TAUP, represent the unitary matrix P as a product of elementary reflectors. See Fur-
ther Details. LDA (input) INTEGER The leading dimension of the array A. LDA >= max(1,M).
D (output) REAL array, dimension (NB)
The diagonal elements of the first NB rows and columns of the reduced matrix. D(i) = A(i,i).
E (output) REAL array, dimension (NB)
The off-diagonal elements of the first NB rows and columns of the reduced matrix.
TAUQ (output) COMPLEX array dimension (NB)
The scalar factors of the elementary reflectors which represent the unitary matrix Q. See Further Details. TAUP (output) COM-
PLEX array, dimension (NB) The scalar factors of the elementary reflectors which represent the unitary matrix P. See Further
Details. X (output) COMPLEX array, dimension (LDX,NB) The m-by-nb matrix X required to update the unreduced part of A.
LDX (input) INTEGER
The leading dimension of the array X. LDX >= max(1,M).
Y (output) COMPLEX array, dimension (LDY,NB)
The n-by-nb matrix Y required to update the unreduced part of A.
LDY (output) INTEGER
The leading dimension of the array Y. LDY >= max(1,N).
FURTHER DETAILS
The matrices Q and P are represented as products of elementary reflectors:
Q = H(1)H(2) . . . H(nb) and P = G(1)G(2) . . . G(nb)
Each H(i) and G(i) has the form:
H(i) = I - tauq * v * v' and G(i) = I - taup * u * u'
where tauq and taup are complex scalars, and v and u are complex vectors.
If m >= n, v(1:i-1) = 0, v(i) = 1, and v(i:m) is stored on exit in A(i:m,i); u(1:i) = 0, u(i+1) = 1, and u(i+1:n) is stored on exit in
A(i,i+1:n); tauq is stored in TAUQ(i) and taup in TAUP(i).
If m < n, v(1:i) = 0, v(i+1) = 1, and v(i+1:m) is stored on exit in A(i+2:m,i); u(1:i-1) = 0, u(i) = 1, and u(i:n) is stored on exit in
A(i,i+1:n); tauq is stored in TAUQ(i) and taup in TAUP(i).
The elements of the vectors v and u together form the m-by-nb matrix V and the nb-by-n matrix U' which are needed, with X and Y, to apply
the transformation to the unreduced part of the matrix, using a block update of the form: A := A - V*Y' - X*U'.
The contents of A on exit are illustrated by the following examples with nb = 2:
m = 6 and n = 5 (m > n): m = 5 and n = 6 (m < n):
( 1 1 u1 u1 u1 ) ( 1 u1 u1 u1 u1 u1 )
( v1 1 1 u2 u2 ) ( 1 1 u2 u2 u2 u2 )
( v1 v2 a a a ) ( v1 1 a a a a )
( v1 v2 a a a ) ( v1 v2 a a a a )
( v1 v2 a a a ) ( v1 v2 a a a a )
( v1 v2 a a a )
where a denotes an element of the original matrix which is unchanged, vi denotes an element of the vector defining H(i), and ui an element
of the vector defining G(i).
