The original code required the use of firls() in certain (not atypical) cases.

Might the remez() function fail to produce useful results mostly because complexity is incorrectly calculated?
--> complexity = sum(csdsize2(f1)) + (2*n1-1)*(n2+sum(csdsize2(f2))-1)

csdsize2() was created to facilitate the complexity calculation, but the original logic was never really well understood. Operations on the {.val,.csd} structure arrays are somewhat difficult to decipher.
