I've been trying to find the mathematics/theory behind the matlab filloutliers function, but could not find anything about it.
Does anyone know what the theory behind this function is, besides that it detects and replaces outliers?

Lets considere "spline" as a "fill method" . The documentation says that it detects and replaces outliers by filling it using piecewise cubic spline interpolation. Does the function in this case delete the outliers and fills them accoring to a piecewise cubic spline interpolation, or does it also consider the value of these outliers?

It only considers the values of the non-outliers. The code that does the work is in toolbox/matlab/datafun/private/locateoutliers.m
