I would like to compute the phase of a complex number using boost::compute
here is my attempt, I expect the result to be equal to atan2(0.5f):
namespace bc = boost::compute;
bc::vector<std::complex<float>> vec{ {1.0f, 2.0f} };
bc::vector<float> result(1);
bc::transform(vec.begin(), vec.end(), result.begin(), bc::atan2<float>());
but I get a compilation error claiming "Non-unary function invoked one argument"
I think you can also use Boost.Compute's lambda expressions for this:
float2
is bassically a complex in Boost.Compute. You can also check test_lambda.cpp.
