C6657 FFT参数问题

Other Parts Discussed in Thread: FFTLIB

我在fftlib中找到了 fft_sp_cmplx_notwid_br函数,

void fft_sp_cmplx_notwid_br(double *inp,unsigned int n, double *outp, double *coeff) {
unsigned int interrupt_context;

我存放复数用的方法是定义了结构体

#ifdef _LITTLE_ENDIAN
typedef struct _CPLXF
{
float imag;
float real;
} cplxf_t;

#endif

请问各位TI工程师们,如何使用参数为double *的函数,同样请问如何使用参数为const float *的函数,如dsplib的DSPF_sp_vecmul函数
