24 class GaussMultipleIntegration from math
26 -- This class implements the integration of a function of multiple
27 -- variables between the parameter bounds Lower[a..b] and Upper[a..b].
28 -- Warning: Each element of Order must be inferior or equal to 61.
31 uses Vector from math,
32 IntegerVector from math,
33 MultipleVarFunction from math,
36 raises NotDone from StdFail
40 Create(F: in out MultipleVarFunction; Lower, Upper: Vector;
43 -- The Gauss-Legendre integration with Order = points of
44 -- integration for each unknow, is done on the function F
45 -- between the bounds Lower and Upper.
47 returns GaussMultipleIntegration;
50 ---Purpose: returns True if all has been correctly done.
57 ---Purpose: returns the value of the integral.
65 Dump(me; o: in out OStream)
66 ---Purpose: Prints information on the current state of the object.
