class SimpleApprox from AdvApprox
|

|
---Purpose: 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
