I generated a FFT Signal of sampling frequency 1kHz for 65536 column vectors of a time domain signal. I want to apply segmentation on this FFT signal to 1024 parts before applying feature extraction.

Yes but I need the MATLAB code to segment this signal into 1024 non overlapping bins, each of 64 vectors as mentioned.

fs = 1000;
t = 0:1/fs:65.536-1/fs;
x = sin(2*pi*50*t);
X = fft(x);
X_1024 = reshape(X,1024,[]);
% X_1024 --> [1024x64]
