fmincon optimization with integral function
显示 更早的评论
I'm trying to minimize the area of a function using fmincon and integral function My function is as given below
func = @(x)integral((@(l)(x(1)-l)),x(2),x(3),'ArrayValued',true);
...
[x, fval] = fmincon(func,x0,A,b,Aeq,beq,lb,ub,nonlcon);
The error I'm seeing is -
Input arguments to function include colon operator. To input the colon character, use ':' instead.
Error in fmincon (line 635) initVals.nceq = ceqtmp(:);
Error in flattop (line 15) [x, fval] = fmincon(func,x0,A,b,Aeq,beq,lb,ub,nonlcon);
Error in Load_Shift_Flat (line 118) [pnew, tstart, tending] = flattop(peak_load,tsta,tend,pmax,e(i-1));
I'm trying to optimize for 3 variables and l is an array which is an input to the flattop function

It looks like the problem is in your nonlcon. What have you passed there?
The error would be consistent with your nonlcon returning a function handle when a value is expected.

Remove the @(x) in the definition of ceq in your nonlcon. You are returning a handle to a function where you need to return a definite value for the current input.
