class GaussSetIntegration from math
---Purpose: -- This class implements the integration of a set of N
-- functions of M variables variables between the
-- parameter bounds Lower[a..b] and Upper[a..b].
-- Warning: - The case M>1 is not implemented.
uses Vector from math,
IntegerVector from math,
FunctionSet from math,
OStream from Standard,
NotDone from StdFail
raises NotDone, NotImplemented
is
Create(F: in out FunctionSet; Lower, Upper: Vector;
Order: IntegerVector)
---Purpose:
-- The Gauss-Legendre integration with Order = points of
-- integration for each unknow, is done on the function F
-- between the bounds Lower and Upper.

IsDone(me)
---Purpose: returns True if all has been correctly done.
---C++: inline
returns Boolean

Value(me)
---Purpose: returns the value of the integral.
---C++: inline
---C++: return const&
returns Vector

---Purpose: Prints information on the current state of the object.
