What is inverse Fourier transform of function?
The inverse Fourier transform is defined by(12.4)ℱ−1[g](x)=1(2π)n· ∫ℝnf(ξ)eiξxdξ.
X = ifft( Y , n ) returns the n -point inverse Fourier transform of Y by padding Y with trailing zeros to length n .
X = ifft( Y , n , dim ) returns the inverse Fourier transform along the dimension dim .
For example, if Y is a matrix, then ifft(Y,n,2) returns the n -point inverse transform of each row.
