Hi everybody,

In case u didn’t know, CNC’s code solve the sparse linear equations using CUDA.

I tried the CNC code and when i constructed the simplest example to solve. The code does not output the correct vector. I wonder why this is happening. I didn’t change anything to the Visual studio project and just add a new test data file to test. It’s as follows:

2

4

a 0 0 1

a 0 1 1

a 1 0 1

a 1 1 -1

b 0 2

b 1 0

And the result is : array[0] = 2, array[1] = 0, which is not correct. This is a simple equation"x+y = 2; x-y = 0".

If anybody is using CNC’s code and had similar problems, please reply. Really appreciated.
