Hi All,
I've a problem and I can't find the answer anywhere. Let we say, that we've some defined interval [ xa, xb ] in which values of a function f(x) must be less than ymax (f(x) < ymax) - this are the design criterias. Now the point is, that I want to use any polynomial or rational function to met such assumption. So e.g. practical case: I want to use such a function f(x)=ax4+b2x3+cx+d in situation, where in range [0, 10], values of function are less than -20, and beyond this interval - values should be greater. How can I calculate values of a,b,c,d parameters ?
Best Regards,
E.
