This is my first time too that's why facing many computational bottlenecks. But its fun at the end of the day
One possible solution is to split the matrix file and do parallel processing on those split files.
Another which I am currently doing is to do away with the matrix file itself and change my source program which actually created the matrix file to create the sparse file. This matrix is really really huge..blew off all my disk space too

I just did some tweaks to my C program and made it more efficient. Instead of creating that huge matrix file, I read in the files with the rows and columns information
Code:
2 3
1 1
1 3
2 2
3 1
I then read wrote my program in such a way, that I get the output as I have given above:
and BINGO!!! It worked pretty much well and occupied just 600MB of disk space and the program took just few minutes to execute whereas my last program that generated the BIG matrix file ran for the entire night. I am not posting my C code here as it won;t make sense and people cannot understand what the entire purpose of the program is.
Hi guys I want to print the values by using this script but its giving the no of rows and columns as input instead of values

Hi
My pipe delimited .txt file contains rows with 10 columns.
Can anyone advise how I output to file only those rows with the letters ‘ci'
as the first 2 characters in the 3rd column ?
Many thanks (4 Replies)
Hello,
I want to extract several columns and rows from a huge tab delimited file
for example: I want to print from from column 3 to 68 till row number 30.
I have tried using cut command but it was extracting whole 3rd and 68th column.
Please suggest a solution.

Hi all,
I have a large matrix of 720 x 25. I want to get sum of range of rows and columns. Like, I need sum of all columns and row number 2 to 21, then leaving 22nd row, again sum of all columns and row number 23 to 42 again leaving 43rd row and then sum of 44th to 63.

Hi all, I'm pretty much a newbie to UNIX. I would appreciate any help with UNIX coding on comparing two large csv files (greater than 10 GB in size), and output a file with matching columns.
I want to compare file1 and file2 by 'id' and 'chain' columns, then extract exact matching rows'... (5 Replies)

glpushmatrix
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.
