Can fmincon (optimization tool) be used over one variable.?

Asked by Deviprakash Upadhyaya on 4 Feb 2013

I am taking uniform thickness of a singly curved cylindrical Shell as a design variable for optimization with Static(Vertical deflection) and dynamic(frequency) as Constraints.

Accepted answer

Yes.

However, I am not sure that this is the answer you wanted. Feel free to ask again with more detail. Meanwhile, you might be able to answer some of your own questions by looking at examples in the documentation.

Alan Weiss, it will help me a lot if you can give a example for single variable constrained optimization using fmincon.

Alan Weiss on 11 Feb 2013

Usually a single-variable problem falls in the domain of fminbnd. But if you really want to use fmincon:

 lb = 5;
 ub = 15;
 x0 = 10;
 [x,fval] = fmincon(@sin,x0,[],[],[],[],lb,ub)
