Dear Lester,

Yes this behavior of fzero, passing extra arguments, in Matlab is known [1],
e.g. Matlab allows:

mysin = @(x,a,b) a*sin(x)+b
fzero (mysin, 1, [], 2, 0.2)

Octave doesn't. Matlab still supports this behavior maybe for legacy reason,
but does not document this and recommends using other methods [2], that
Octave supports as well. For your Example:

allequ2 = @(x) allequ(x,Y1(j,i),zb(j),zt(j),surpor(j),c(j));
yy = fzero(allequ2,Y2(j,i),options);

HTH, Kai
