Error using ofun
Too many input arguments.
Error in AFO1 (line 181)
y(i)=option.fobj(x(i,:),option,data);
Error in main_AFO (line 31)
[bestY,bestX,recording]=AFO1(x,y,option,data);
my fuction is
function f = ofun(x) % objective function (minimization)
of =2.6773*x(1)+3.1007*x(2)+3.2178*x(3)+ 3.8021*x(4)+3.6727*x(5)+3.0442*x(6)+1.6362*x(7)+3.0479*x(8)+3.3917*x(9)+3.7468*x(10)+3.8989*x(11)+3.1073*x(12)+3.3207*x(13)+ 1.6382*x(14);

You constructed your own main_AFO file.m file, probably based upon the main1.m in the File Exchange contribution.
The main1.m source code has
[lb,ub,dim,fobj] = Get_Functions_details(option.F);
%stuff
option.fobj0=fobj;
option.fobj=@fitFCN_BX;
I suspect that you instead did
options.fobj = @fobj;
but that you instead should have done
option.fobj0 = @fobj;
option.fobj=@fitFCN_BX;
Unfortunately once again someone has asked us to debug code without providing us with a copy of the code, so we can only guess about the details.

You need to replace
option.fobj = @ofun;
with
option.fobj0 = @ofun;
option.fobj = @fitFCN_BX;

Ran in:
I cannot reproduce your issue. When I try the following, I do not get an error:
x = randn(20,1);
r = ofun(x)
r = 3.5276e+05
function f = ofun(x) % objective function (minimization)
of =2.6773*x(1)+3.1007*x(2)+3.2178*x(3)+ 3.8021*x(4)+3.6727*x(5)+3.0442*x(6)+1.6362*x(7)+3.0479*x(8)+3.3917*x(9)+3.7468*x(10)+3.8989*x(11)+3.1073*x(12)+3.3207*x(13)+ 1.6382*x(14);
