This one works:

  pwelch (sin(1:1000)+rand(1,1000),[],1000,[],[],0,'half','db','linear')

while this one should, but does not:

  pwelch (sin(1:1000)+rand(1,1000),[],1000,[],[],0,[],[],'linear')


Yes, the error is like the one you mention, but even if you go and
correct the trivial bug that gives this error, you find out that most of
the code checking for arguments should be rewritten.
