Hi Guys,

I am new with the IMKL 8.0 library using MS Visual C++ Version 7.1

I am able tu run the Paradiso Example Sparse Direct.cpp

Then I proceeded to modify the program to read in a matrix and perform a similar calculation. The matrix is a 10 by 10 that looks like this:

12368463120
2100000000
3010000000
6001000000
8000100000
4000010000
6000001000
3000000100
1000000010
20000000001

The B vector looks like this:

1
2
0
0
3
6
5
1
1
6

I am trying to learn how to use this but (under the example program everything works) when I modified to read this matrix in I get an error when performing

error = dss_factor_real( handle, type, values );

The message that I get is: The program '[788] Paradiso Example Sparse Direct.exe: Native' has exited with code -1 (0xffffffff)

Any ideas, the code is set here below:

Thanks in advance..
