I'm using an inline file here, so you'll have to adapt it if you want the file from the command line or where ever. First key of %data is the row, second is the column.
Hi everybody,
I have a matrix called @matrix dinamically built in PERL, so I don't know its exact sizes. It is a 2-dimensional matrix, so its elements are for example:
$matrix
$matrix
$matrix
$matrix
$matrix
etc...
I know i can get the number of the rows of the matrix with the... (2 Replies)
Hello guys,
I have in PERL an associative 2-dimensional array, called matrix. The array (actually the matrix) is made up like this
matrix = x;
matrix = y;
matrix = w;
matrix = z;
...
but the names a, b, c, d are set just at runtime.
The question is: how can i get all the keys of... (2 Replies)
hi there
I'm very new in programing and i've started with awk.
I'm processing 200 data files and I need to do some precessing on them.
The files have 3 columns with N-lines
for each line a have on the first and second value is the same for all the files and only the third is variable. like... (2 Replies)
I have columnar data in arrays perl, Example -
@a = (1,2,3);
@array1 = (A,B,C);
@array2 = (D,E,F);
@array3 = (I,R,T);
I want the data to be formatted and printed as
1 A D I
2 B E F
3 C F T
and so on... (8 Replies)
Greetings, salutations.
I have a 3 column csv file with ~13 million rows and I would like to generate a correlation matrix. Interestingly, you all previously provided a solution to the inverse of this problem. Thread title: "awk? adjacency matrix to adjacency list / correlation matrix to list"... (6 Replies)
Hi All,
I have a question. I need to add 3 matrices of size 2000 x 2000. (i.e) 2000 rows and 2000 columns using Perl::PDL module. I used the following perl script
#!/usr/bin/perl -w
use strict;
use warnings;
use PDL;
use PDL::Matrix;
if ( @ARGV != 3 ) {
die 'Two matrix files are... (1 Reply)
Dear all,
I'm new in perl scripting and I'm trying to creating a matrix from a 3 column file sorting data in a particular manner. In the final matrix I need to have the first column "IDs" on the header of the columns and the second column values on the header of each row. And the value fo the... (2 Replies)
Hello all,
I have a tricky question! (at least for me it is!). I'll try to explain it carefully here. Hope you can help me solving the whole or even parts of it! Here it is:
I have a big input 0\1 table as a very simplified one is shown below:

GLPUSHMATRIX(3G)GLPUSHMATRIX(3G)NAME
glPushMatrix, glPopMatrix - push and pop the current matrix stack
C SPECIFICATION
void glPushMatrix( void )
C SPECIFICATION
void glPopMatrix( void )
DESCRIPTION
There is a stack of matrices for each of the matrix modes. In GL_MODELVIEW mode, the stack depth is at least 32. In the other modes,
GL_COLOR, const(PROJECTION), and GL_TEXTURE, the depth is at least 2. The current matrix in any mode is the matrix on the top of the stack
for that mode.
glPushMatrix pushes the current matrix stack down by one, duplicating the current matrix. That is, after a glPushMatrix call, the matrix
on top of the stack is identical to the one below it.
glPopMatrix pops the current matrix stack, replacing the current matrix with the one below it on the stack.
Initially, each of the stacks contains one matrix, an identity matrix.
It is an error to push a full matrix stack, or to pop a matrix stack that contains only a single matrix. In either case, the error flag is
set and no other change is made to GL state.
ERRORS
GL_STACK_OVERFLOW is generated if glPushMatrix is called while the current matrix stack is full.
GL_STACK_UNDERFLOW is generated if glPopMatrix is called while the current matrix stack contains only a single matrix.
GL_INVALID_OPERATION is generated if glPushMatrix or glPopMatrix is executed between the execution of glBegin and the corresponding execu-
tion of glEnd.
