'Not enough input arguments' error in GlobalSearch function

I am trying to obtain global minima for a function using fmincon and globalsearch functions. But, there seems to be some error in function definition when I use CreateOptimProblem command. The error is

Not enough input arguments.

Error in inclndbackfill_inclinedwall>inclinedbckfill_inclwall (line 37)

alps(1:M)=X(1:M);

Code is given below. ( the function code is really big, so i m not including the entire one)

N=4; M=3;
A=[]; b=[];
Aeq=[]; Beq=[];
x0=[0*ones(1,M)    0*ones(1,N)];    lb=[0*ones(1,M)  0*ones(1,N)];    ub=[1.57*ones(1,M)  1.57*ones(1,N)];
opts=optimoptions(@fmincon,'Algorithm','sqp');
problem=createOptimProblem('fmincon','objective',inclinedbckfill_inclwall,'x0',x0,'lb',lb,'ub',ub,'options',opts);
gs=GlobalSearch;
[x,fval]=run(gs,problem);

function f=inclinedbckfill_inclwall(X)
N=4;
M=3;
alps(1:M)=X(1:M);
alp(1:N)=X(M+1:M+N);
...................................
end

problem = createOptimProblem('fmincon', 'objective', @inclinedbckfill_inclwall, 'x0', x0, 'lb', lb, 'ub', ub, 'options', opts);

I tried this way, but then it shows another error;

Error using sqpInterface

Objective function is undefined at initial point. Fmincon cannot continue.

Error in fmincon (line 871)

[X,FVAL,EXITFLAG,OUTPUT,LAMBDA,GRAD,HESSIAN] = sqpInterface(funfcn,X,full(A),full(B),full(Aeq),full(Beq), ...

Error in globaloptim.globalsearch.globalsearchnlp

Error in GlobalSearch/run (line 340)

globaloptim.globalsearch.globalsearchnlp(FUN,X0,A,B,Aeq,Beq,LB,UB,NONLCON,options,localOptions);

Error in inclndbackfill_inclinedwall (line 30)

[x,fval]=run(gs,problem);

Caused by:

Failure in initial call to fmincon with user-supplied problem structure.

So,what could be the reason here?

[Torsten]

The reason is that your objective function is undefined at the initial point as clearly stated by the error message.

Try what you get back when you call

inclinedbckfill_inclwall(x0)

before the line

[x,fval]=run(gs,problem);

Yes, got it. Thanks
