fmincon, help please

Hi,

I am trying to calculate the minimum of a function with multiple variables, the only constraints I have are the upper and lower bounds of the variables. The problem I am having is that fmincon does not change the input value from the initial guess value I give it.

This is the output I get:

initGuess =

    0.6159


x =

    0.6159


x =

    0.6159


Initial point is a local minimum that satisfies the constraints.

Optimization completed because at the initial point, the objective function is non-decreasing
in feasible directions to within the selected value of the function tolerance, and
constraints are satisfied to within the selected value of the constraint tolerance.

This is my call to fmincon:
A = [];
b = [];
Aeq = [];
beq = [];
lb = 0;
ub = 1;
initGuess = 0.6159;
options = optimset('TolX',1e-12,'TolCon',1e-12,'TolFun',1e-12,'Algorithm','interior-point');
[optAM,optBC] = fmincon(@(x) cmpBC(x,epochDate,epochDate2,root,rvfm),[initGuess],A,b,Aeq,beq,lb,ub,nonlcon,options);

I tried multiple initial guesses and the same thing happens, please help not sure how fix this.
