Details:
the function specgram() started with no additional parameters but the data
vector throws error (and stops the parent script from running) when given a
vector of 384 items or less.
For 256 items and less, these error messages are shown:
specgram(rand(256,1))
error: 'xdata' undefined near line 179 column 49
error: evaluating argument list element number 5
error: called from:
error: /usr/local/share/octave/3.8.2/m/image/image.m at line 179, column 5
error: /usr/local/share/octave/3.8.2/m/image/image.m at line 116, column 10
error: /usr/local/share/octave/3.8.2/m/image/imagesc.m at line 97, column
12
error: /home/kaefert/octave/signal-1.3.0/specgram.m at line 167, column 5
for the default plotting engine, everything above 256 items outputs a plot,
but with gnuplot (which I need for beeing able to plot in the background
without producing an x window & through parcellfun()) after between 267 and
384 this errors are shown:
multiplot> plot "-" binary array=2x128 scan=yx origin=(0.5,0) dx=0
dy=0.0078125 using 1 title "" with image; ;
line 0: Sample period must be positive. Try `flip` for changing direction
and lots of crazy caracters that produce:
line 0: invalid character
errors as a result
