WebNo. You cannot use fit to perform such a fit, where you place a constraint on the function values. And, yes, a polynomial is a bad thing to use for such a fit, but you don't seem to care. Regardless, you cannot put a constraint that the MAXIMUM value of the polynomial (or minimum) be any specific value. The problem is, the maximum is a rather ...
