error :Too many output arguments

I am getting an error as "too many output arguments" even though the function has declared for giving that given number of outputs

[D(1) ,alpha_n(1),M(1),cl(1)]= aeronew(ay(1),az(1),ht(1),v(1),time(1),alpha,M,cl); (this is the function call)

function [D,alpha_new, mach_new, cl_new] = aeronew(ay,az,ht,velocity,time,alpha,M,cl,i)(this is the function defenition

You should get only one result from:

which aeronew -all

If you get more than one, that may point you to the problem.
