The documentation of the toolbox says that only data till the last marked artefact is used for filter computation. But it does not seem to be the case. Mask generated has 0s in unmarked segments which is later used in creating the matrix of clean (artefact free) data. Hence, unmarked segments are treated as clean.

When applying mwf_compute to certain data covariances Ryy and Rnn could be non-symmetric. Mathematically it is not possible, but precision issues in MATLAB may cause it. This will lead to complex eigen values in GEVD.
Suggestion: force Ryy and Rnn to be symmetric. For eg:
Ryy = (Ryy+Ryy')./2;
