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. -- Francesco Potortì (ricercatore) Voice: +39 050 315 3058 (op.2111) ISTI - Area della ricerca CNR Fax: +39 050 315 2040 via G.
