AdvApprox_SimpleApprox Class Reference

Approximate a function on an intervall [First,Last]
The result is a simple polynomial whose degree is as low as
possible to satisfy the required tolerance and the
maximum degree. The maximum error and the averrage error
resulting from approximating the function by the polynomial are computed
