示例1: compare
int compare(CollOfScalar scal, double sol[],
int sol_size,
std::string test)
{
// Test size:
if ( scal.size() != sol_size ) {
std::cout << "Error in valsOnGrid.cpp - testing " << test << "\n";
std::cout << "\tThe collection is of wrong size!\n";
std::cout << "\tSize is " << scal.size() << " but should be " << sol_size << "\n";
return 1;
}
// Testing indices
std::vector<double> host = scal.copyToHost();
std::cout << "CollOfScalar " << test << " is the following:\n";
bool correct = true;
for (int i = 0; i < host.size(); ++i) {
std::cout << host[i] << " ";
if (i < sol_size) {
//if (host[i] != sol[i]) {
if ( fabs(host[i] - sol[i]) > 1000*std::numeric_limits<double>::epsilon() ) {
