CCS/TMS320F28379D: The function RFFT_adc_f32 and the related magnitude

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hi,

I use the example in Controlsuite 'RFFT_ADC_rt', and I am confused about the magnitude result, it should be matched the result I calculated in the matlab but it is different.(I have take quantilization into consideration)

My question is that, the RFFT_adc_f32 function is trying to calculate  FFT of unsigned input into floating result, and then the RFFT_mag function try to find out the result, but when I try this example, the result  differ from the MATLAB result, so anybody met the problem before?

Regards,

Karen
