FT_FREQINTERPOLATE
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_freqinterpolate”.
FT_FREQINTERPOLATE interpolates frequencies by looking at neighbouring values or simply replaces a piece in the spectrum by NaN. Use as freq = ft_freqinterpolate(cfg, freq) where freq is the output of FT_FREQANALYSIS or FT_FREQDESCRIPTIVES and the configuration may contain cfg.method = 'nan', 'linear' (default = 'nan') cfg.foilim = Nx2 matrix with begin and end of each interval to be interpolated (default = [49 51; 99 101; 149 151]) To facilitate data-handling and distributed computing you can use cfg.inputfile = ... cfg.outputfile = ... If you specify one of these (or both) the input data will be read from a *.mat file on disk and/or the output data will be written to a *.mat file. These mat files should contain only a single variable, corresponding with the input/output structure. See also FT_FREQANALYSIS, FT_FREQDESCRIPTIVES, FT_FREQSIMULATION
