remez function broken?

[Dean Parsons]

Is Scilab's remez function broken? When I try to use it it always returns an empty matrix [ ].

For example:

-->nc = 21;
 
-->ngrid=10240;
 
-->fg = linspace(0,0.22,ngrid/2);
 
-->fg = [fg linspace(0.25,0.5,ngrid/2)];
 
-->x = fg(1:ngrid/2)/128;
 
-->ds(1:ngrid/2)=ones(1:ngrid/2);
 
-->ds(ngrid/2+1:ngrid)=zeros(1:ngrid/2);
 
-->wt=ones(fg);
 
-->an=remez(nc,fg,ds,wt)
 an  =
 
     []
