Let us consider the function f(x), defined as f(x)=x for negative x+10, f(0)=10, and f(x)=ln(1+x)+10 for positive x. It is clear that f(x) is a concave and smooth function.
I coded it as
subject to blah blah blah
However, since x is posed in “if” statement, error occurs. Is there any method to implement CVX for the case where the objective function is differently defined according to design variable’s region.
