I need to do fft of a complex number ....

I've come across the below guide on DSP_fft16x16 ... one thing I don't understand is that there a w argument on section 4.3 which is described as "w[2*nx]Pointer to complex Q.15 FFT coefficients." (I attached a snapshot) I just need to know what is W doing because in Matlab I just have to pass an array of real/complex numbers and that's it. Please let me know your comments.

Also checked the fft_example.c under examples/fft_ex but couldn't make much sense of what is going on... can you pleas let me know which example is applicable to a TMDSEVM6678 device.

Best Regards,
