error msg:

Error:

Function definitions in a script must appear at the end of the file.

Move all statements after the "nclon1" function definition to before the first local function

definition.

Hi Aakash,

Any function definition in a script must be at the end. You may not follow a function definition with unrelated code.

Please refer to this link as this question has already been answered.

Hope this solves it.

c = r(1)^2 + r(2)^2 + r(3)^3 + r(4)^4 + r(5)^5 - 1;

ceq = [];

end

after i did this ,some other error occured

Unrecognized function or variable 'getIpOptions'.

Error in fmincon (line 832)

options = getIpOptions(options,sizes.nVar,mEq,flags.constr,defaultopt,10,0.01);

Error in the line below:

r= fmincon(objective,r0,A,b,Aeq,beq,lb,ub,nonlcon);

Do you have the optimization toolbox installed?
