mscohere - Magnitude-squared coherence - MATLAB

Use a Hamming window of length 100 to window the data. mscohere returns one coherence function for each output channel. The coherence functions reach maxima at the frequencies shared by the input and the output.

MSCOHERE - DADiSP

MSCOHERE estimates the magnitude-squared coherence function between an input series x and a corresponding output series y using the Welch method (see PWELCH). The input and output series are divided into overlapping s...

Cross Spectrum and Magnitude-Squared Coherence

Both Welch's overlapped segment averaging (WOSA) and multitaper techniques are appropriate. mscohere implements a WOSA estimator. Set the window length to 100 samples.
