pass double symbolic expression to paretosearch

1 view (last 30 days)
hi at all.
need to pass two symbolic expression that i must try to minimize with pareto search.
with matlabFunction i turn the symbolic expression to matlab numeric function but there is no way to pass this two function to paretosearch.
Can anyone please help me with simple example?
i reproduce it for me .
thank at all

It depends on how you created your symbolic expressions.
  • If you have two expressions, say obj1 and obj2, then two runs of matlabFunction returns two function handles, say funobj1 and funobj2. You can pass these to paretosearch by using the handle
twoobj = @(x)[funobj1(x),funobj2(x)];
sol = paretosearch(twoobj,2,...))
  • If you have a 2-D row vector output to your objective function named obj, then matlabFunction returns a function handle funobj that is all ready for paretosearch:
sol = paretosearch(funobj,2,...)
If this doesn't work for you, please ask again with more detail, such as exactly which size inputs and outputs your functions expect, how you call matlabFunction, and how you call paretosearch.
