class GaussMultipleIntegration from math
---Purpose:
-- This class implements the integration of a function of multiple
-- variables between the parameter bounds Lower[a..b] and Upper[a..b].
-- Warning: Each element of Order must be inferior or equal to 61.
uses Vector from math,
IntegerVector from math,
MultipleVarFunction from math,
OStream from Standard
raises NotDone from StdFail
is
Create(F: in out MultipleVarFunction; 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.
