I have traced it down to the call to syredi, which is a fortran function. When run the example from the help file I get different results from scilab 5.4 and scilab 4.</div><div><br></div><div><br></div><div>// Scilab 5.4</div>[fact,b2,b1,b0,c1,c0,zzeros,zpoles]=syredi(1,4,[2*%pi/10,4*%pi/10,0,0],0.02,0.001);<div>disp(b1)</div><div>--> [2 2 1]</div><div><br></div><div>// Scilab 4.1</div><div>[fact,b2,b1,b0,c1,c0,zzeros,zpoles]=syredi(1,4,[2*%pi/10,4*%pi/10,0,0],0.02,0.001);<div>disp(b1)</div></div><div>--> [ - 0.5354229 0.3489640 1. ]</div><div><br></div><div>The poles end up correct, but the zeros are rounded or casted to int or something like that.</div><div><br></div><div>Does anyone know anything about this? Should I report it as a bug?</div><div><br></div><div>This turns out to break a lot of code for me, but in a very non-obvious way.</div><div><br></div><div>Best regards,</div><div>Arvid<br><div><br><div apple-content-edited="true">
