fftlib函数库怎样使用有例子吗，可以替换opencv中dft函数吗？

我想对一个浮点数矩阵做傅里叶变换，

fft_plan_t fft_sp_plan_2d_r2c (intN1,/* FFT size */intN2,/* FFT size */intmode,/* FFT_DIRECT or FFT_ECPY */fft_callout_tfxns
);

int fft_sp_2d_r2c_ecpy (/* int N1; FFT size *//* int N2; FFT size *//* fft_para_mix_bs_t para1; *//* fft_para_mix_bs_t para2; *//* float *data; input/output pointer *//* float *workbuf; working pointer *//* float *workbuf_w; working buffer pointer *//* float *workbuf_t; working buffer pointer *//* float *tw; twiddle pointer *//* float *tw_w; twiddle buffer pointer *//* float *Bn; Bluestein pointer *//* float *Bn_w; Bluestein buffer pointer *//* float *workbuf_bn; Bluestein scratch pointer */fft_param_u u,void *edmaState
 );

这两个函数怎样调用

抱歉，没有例程，请参考fftlib_3_1_0_0\docs\FFTLIB_Users_Manual.html文档说明
