Programming :: ARPACK++ - Error "Matrix Data Contains Inconsistencies"
Jun 26, 2011
In the following code, I am trying to define a matrix in CCS (which is equivalent to CSR for a symmetric matrix, right ?) in ARPACK++.
I have installed and patched ARPACK++. (The matrix is not sparse, but still it should not give an error)
[code]...
Why is this so ? I have checked the values of ia and ja by running intel MKl on the matrix to find the CSR (again, CSR=CCS for symmetric matrix, right ?--I am asking this because ARPACK++ uses CCS, not CSR), and the values are the same. Is this some problem of 0 and 1 indexing ? Does ARPACK++ use 1 indexing?

I just can't find... why is my code seg-faulting?
PHP Code:
/*
Code name: Assignment #7.
File name: slice.c
Program name: Matrix multiplication (parallel version).
Version: 1.
[Code]...
Is giving my a seg-fault right at the ending point where I do the final gather from the MASTER processor.

i did this code:
reads 1 matrix 2x2 and print!
Code:
# include <stdio.h>
int main()
{
int t, i, M[2][2];
int big[2];
[Code]....
Now i want to create 2 vectors:
1 vector: has the biggest number of every line on the matrix
2 vector: has the lowest number of every column on the matrix

I'm writing a command-line flash card program in Python. I've tried many existing applications, but none fit my specialized needs.
All of the words I'd like to study are manually added to a text file (study.txt). Each time the software is loaded, it checks for new words in that file and also compares them to a dictionary (a tab-separated file, dictionary.txt), and adds that to a matrix. The flash cards are thus automatically generated from study.txt and dictionary.txt.
Now, the software must manage lots of information about each word I'd like to study and add new information made while interacting with the program (such as when that word should be studied next).
That seems easy to put into a matrix. But what is the best way to put that information in a place where I can pull it back when I run the software tomorrow? Do I need to save the matrix to a CSV file, then convert the CSV file back to a matrix the next time the application is run?

This is one of the strangest problems I've run into while programming. Maybe there's just something wrong with my version of gcc or something.
The main problem comes at this point in the code:
Code:
po = makePoFromScorbotXYZPR(X, Y, Z, P, R);
h = makeHB2GFromPo(po);
printf("%le", *h[1][0]); //##################################### Here it has the right value
printf("%s", "

I use Codeblocks as IDE environment for my C programs. I recently added the matrix library Meschach, but unfortunately the headers are not found during compiling/linking process.For instance, my generic program is the one below:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <matrix.h>
[code]...
This program generates the following error during compilation:
Quote:
main.c|3|error: matrix.h: No such file or directory|
And the declaration <matrix.h> is supposed to include the Meschach library, according to the instruction on the below link:
[URL]
Furthermore, I see on folder /usr/include the following:File stdio.h;
Filestdlib.h;
Folder "Meschach", which contains the file "matrix.h".

I have a 10x2 matrix, I create said matrix and fill it one column with zeros and the other with ones, now when I print the matrix I get this:
column 1:
0,0,0,0,0,0,0,0,1,1
column 2:
1,1,1,1,1,1,1,1,1,1
The first two rows of the second column are being replaced into the last two rows of the first column, now I even checked in visual studio and it works fine there. A friend tried my code and he gets it even worse:
column 1:
0,0,0,0,1,1,1,1,1,1
column 2:
1,1,1,1,1,1,1,1,1,1
As far as I've seen it must be a problem with GCC, unfortunately I need to have this up and running in GCC no matter what.

I am trying to install a program and it spews out an error about the .obj/matrix.o file.
The output is quoted here:
Code:
The program I was trying to install is a robot simulator which performs lots of matrix manipulation and linear system solving. I followed every step in the installation guide, except for this one:
On Ubuntu, all you need to do is install the following packages from the package manager:
libblas-dev
liblapack-dev
As shown above, I am using RHEL 6, which has different libraries with Ubuntu. I tried "yum search" and installed these libraries instead: lapack.x86_64 : Numerical linear algebra package libraries blas.x86_64 : The Basic Linear Algebra Subprograms library.

I have installed CUDA-BLASTP on C2050.It is giving me an Error:"Bad address Error opening matrix file (null) for reading" while i am running with following query file and dataset:
./CUDA-BLASTP -i ./data/raimondii_contigs.fasta -d ./data/DB_sorted.fasta
and i am using BLOSUM62 as a matrix file which is already present in package.
And getting the error:"Error happened when the number of GPUs is 0" while i am running CUDABLASTP with a part of dataset taking as a query file and dataset is same. above mentioned error is comming from file "CUDA_Blast.cu" included in package.

In mandriva 2008 platform I have installed gcc-g77, liblapack, liblapack-devel, libblas, libblas-devel, arpack, arpack-devel and arpack-static packages. When I link *.f code and these libraries, using g77 compiler with -llapack -lblas -larpack options, everything work. Then when I replaced g77 by gfortran compiler, to be able to work with double precision complex arithmetic, I have got a number of undefined references errors:
[code].....
It looks as if I need to install f95 lapack and arpack libraries. Does anybody know if such rpm packages exist? I cannot find them in the net. If they exist, where is it possible to download them?

Noticed a few discrepancies in the reports generated on my VPS:
Not sure why but the top command gives an extra 3MB for both used and free memory.
Also, notice that there are a total of 29 rows of information returned by the top command for the httpd process. Each row indicates they took an average of 3.5-3.6%. Well, 29 * 3.5 = 101.5%.
How can this be possible for two things:
1) The number greater than 100%.
2) The number doesn't correlate with the memory usage details returned by the top and free commands.

I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.
