Find the column number corresponding to frequencies of a spectral object.
freqtoint(trackdata, j)A spectral object
A vector of frequencies
Jonathan Harrington
This function is used in conjunction with object oriented programming of EMU spectral objects. It should not in general be called from inside a function. Its principal use is to determine the column number(s) corresponding to frequencies for spectral trackdata objects or spectral matrices or the element number for spectral vectors.
freqtoint(fric.dft,1000:2000)
# all frequencies except 1000-2000
freqtoint(vowlax.dft.5, -(1000:2000))
# all frequencies except 1000 Hz
freqtoint(e.dft, -1000)
# the d.c. offset - i.e. column 1
freqtoint(vowlax.dft.5, 0)
# all freqs except the d.c. offset - i.e. not column 1
freqtoint(vowlax.dft.5, -1)
