CUDA -如何转换exp( 1i *x )？

#include <stdio.h>
#include <cuda.h>
#include <cuComplex.h>

__global__ void complexExp(float x_real, float x_imag, float* result_real, float* result_imag) {
    cuFloatComplex x = make_cuFloatComplex(x_real, x_imag);
    cuFloatComplex exp_x = cuCexpf(x);
    *result_real = cuCrealf(exp_x);
    *result_imag = cuCimagf(exp_x);
}

int main() {
    float x_real = 0.0f;
    float x_imag = 1.0f;
    float result_real, result_imag;

    // 分配GPU内存
    float* d_result_real, * d_result_imag;
    cudaMalloc((void**)&d_result_real, sizeof(float));
    cudaMalloc((void**)&d_result_imag, sizeof(float));

    // 调用CUDA核函数
    complexExp<<<1, 1>>>(x_real, x_imag, d_result_real, d_result_imag);

    // 将结果从GPU内存复制回主机内存
    cudaMemcpy(&result_real, d_result_real, sizeof(float), cudaMemcpyDeviceToHost);
    cudaMemcpy(&result_imag, d_result_imag, sizeof(float), cudaMemcpyDeviceToHost);

    // 打印结果
    printf("exp(1i * x) = %f + %fi\n", result_real, result_imag);

    // 释放GPU内存
    cudaFree(d_result_real);
    cudaFree(d_result_imag);

    return 0;
