Hello,

I get an Unhandled exception error when im tring to use the cusparseSnnz function.

my code:

(my matrix is at the size of points_NumberXpoints_Number)

void denseToCsr(cusparseHandle_t handle, float *src,const int points_Number, float *csrVal,int* csrRowPtr,int* csrColPtr)

	int* nnz;

	int *nnzPerVector;

	size_t pitch;

        cudaMallocPitch  ( (void **)  &nnzPerVector, &pitch, points_Number*sizeof(int),1);

        cusparseSnnz(handle,CUSPARSE_DIRECTION_ROW,points_Number,points_Number,descrA,src,points_Number,nnzPerVector,nnz); 

}

Thanks for your advise!
