示例1: sparseCompare
void sparseCompare(array A, array B, const double eps)
{
// This macro is used to check if either value is finite and then call assert
// If neither value is finite, then they can be assumed to be equal to either inf or nan
#define ASSERT_FINITE_EQ(V1, V2) \
if(std::isfinite(V1) || std::isfinite(V2)) { \
ASSERT_NEAR(V1, V2, eps) << "at : " << i; \
} \
array AValues = sparseGetValues(A);
array ARowIdx = sparseGetRowIdx(A);
array AColIdx = sparseGetColIdx(A);
array BValues = sparseGetValues(B);
array BRowIdx = sparseGetRowIdx(B);
array BColIdx = sparseGetColIdx(B);
// Verify row and col indices
ASSERT_EQ(0, max<int>(ARowIdx - BRowIdx));
ASSERT_EQ(0, max<int>(AColIdx - BColIdx));
T *ptrA = AValues.host<T>();
T *ptrB = BValues.host<T>();
for(int i = 0; i < AValues.elements(); i++) {
ASSERT_FINITE_EQ(real(ptrA[i]), real(ptrB[i]));
if(A.iscomplex()) {
ASSERT_FINITE_EQ(imag(ptrA[i]), imag(ptrB[i]));
}
}
freeHost(ptrA);
freeHost(ptrB);
#undef ASSERT_FINITE_EQ
