Index exceeds the number of array elements (1). Caused by: Failure in initial nonlinear constraint function evaluation. FMINCON cannot continue.
My OBJECTIVE FUNCTION: function f=objective2(h,x,F_r,T_r,UA_r,n) options.Display='off'; %FlowStreams x(1)=F_r(1); x(2)=h; ...

How do I maximise Volume of a cylinder such that its Surface Area is less than 10 using fmincon by predicting only either radius or height but not both?
Volume= pi*r*r*h Surface Area= 2*pi*r*(h+r); i am solving a bigger problem. this simple example will help me to solve the bigg...

Solver stopped prematurely. fmincon stopped because it exceeded the function evaluation limit, options.MaxFunctionEvaluations = 3.000000e+03. Unable to rectify this error. Please Help
F_r and T_r are defined. [m n ]=size(F_r); [M N]=size(T_r); My constraints are lengthy but i have checked it is correct. ...

I have a variable named T_t which is of dimension [1 20]. How do i add a normal error with a standard deviation of 1 to it?
I wrote T_t=T_t+1*randn(size(T_t)); But when i check the standard deviation using std( T_t(:) ) i get the value as 51. Pls help...
