pycuda write complex numbers — errors:class “cuComplex” has no member “i”

参考：https://stackoverflow.com/questions/8857063/cuda-pycuda-how-to-write-complex-numbers-errorsclass-cucomplex-has-no#include <pycuda-complex.hpp>template<typename T>
__global__ void kernel(const T * x, const T *y, T *z)
{int tid = threadIdx.x + blockDim.x * blockIdx.x;z[tid] = x[tid] + y[tid];
}typedef pycuda::complex<float> scmplx;
typedef pycuda::complex<double> dcmplx;template void kernel<float>(const float *, const float *, float *);
template void kernel<double>(const double *, const double *, double *);
template void kernel<scmplx>(const scmplx *, const scmplx *, scmplx *);
template void kernel<dcmplx>(const dcmplx *, const dcmplx *, dcmplx *);

This gives you single and double real and complex versions of the trivial kernel and compiles with nvcc something like this:

$ nvcc -arch=sm_20 -Xptxas="-v" -I$HOME/pycuda-2011.1.2/src/cuda -c scmplx.cu
ptxas info    : Compiling entry function '_Z6kernelIN6pycuda7complexIdEEEvPKT_S5_PS3_' for 'sm_20'
