I hope someone can understand and help...

I mean, for loop doesn't work well here... it looks that it stops after a solution... but why??? > > for l=0:sqrt(ni) > x=l; > > y=real(fix(sqrt(ni-x^2))); > if fix(y)==y > z=real(fix(sqrt(ni-x^2-y^2))); > if fix(z)==z > if ni==x^2+y^2+z^2; > n=[x,y,z]; > > result=unique(perms(n),'rows'); > return > end > end > end > end
