Method Math.Transforms.FFT()->rIFFT()
- Method rIFFT
array(float) rIFFT(array(array(float))input)- Description
Returns the inverse FFT of the input array. The input must be complex and guaranteed to generate a real output.
The input is an array. It's first element is the amplitudes and the second element is the phases.
The output is an array of the real values for the iFFT.
- Parameter
real_input The array of floats and/or ints to transform.
- Note
rIFFT(rFFT()) returns the input array scaled by n=sizeof(input array). This is due to the nature of the DFT algorithm.
