This function searches the interior of a signal in an attempt to find a segment that may be used in order to make the signal quasi-periodic. This can be used to reduce the influence of end effects on analyses such as the Hilbert Transform, the Wavelet Transform, the Hilbert-Huang Transform and...

Compute the discrete Fourier transform at specified frequencies, not using fft.Why one may need this?(1) MATLAB fft function computes the amplitude of signals only (no phase).(2) Once having the recorded time-series data, one often uses fft to do the spectral analysis. However, the frequency set...

The function is much faster than Matlab's native (dct, idct, dct2, idct2). It also allows N-D (multidimensional) input.Example:x=randn(100,200,300);y=mirt_dctn(x); % forward DCTx=mirt_idctn(y); % inverse DCTFind more at my home page:http://www.bme.ogi.edu/~myronEnjoy and comment below if you like...

Run this program with a small image of about 100x100 pixels its because though it works on image of any size but for large images the execution time is very high. So if you do not want to wait for a very long time use a small image.
