In what order the transfer of functions take place in Fmincon?
The functions are 1)Fmincon 2)Objective Function 3)Constraint Function. Also in which step does it make use of Initial Guess

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...
