class NumericValue from Expr
|
|
|
|
inherits GeneralExpression from Expr
|
|
|
|
---Purpose: This class describes any reel value defined in an
|
|
-- expression.
|
|
|
|
uses AsciiString from TCollection,
|
|
Array1OfNamedUnknown from Expr,
|
|
Array1OfReal from TColStd,
|
|
NamedUnknown from Expr
|
|
|
|
|
|
raises OutOfRange from Standard

|
Create(val : Real)
|
|
---Level: Advanced
|
|
returns mutable NumericValue;

|
|
|
GetValue(me)
|
|
---Level: Advanced
|
|
returns Real;

|
|
---Purpose: Returns the number of sub-expressions contained
|
|
-- in <me> ( >= 0)
|
|
returns Integer
|
|
is static;
|
|
|
|
SubExpression(me; I : Integer)

Simplified(me)
|
|
---Purpose: Returns a GeneralExpression after replacement of
|
|
-- NamedUnknowns by an associated expression and after
|
|
-- values computation.
|
|
returns any GeneralExpression;
|
|
|
|

|
|
---Purpose: Returns a GeneralExpression after a simplification
|
|
-- of the arguments of <me>.

|
|
---Purpose: Returns a copy of <me> having the same unknowns and functions.
|

---Purpose: Returns the derivative on <X> unknown of <me>
|
|
returns any GeneralExpression;
|
|
|
|
NDerivative(me; X : NamedUnknown; N : Integer)
|
|
---Purpose: Returns the <N>-th derivative on <X> unknown of <me>.

---Purpose: Replaces all occurences of <var> with <with> in <me>
|
|
|
|
Evaluate(me; vars : Array1OfNamedUnknown; vals : Array1OfReal)
|
|
---Purpose: Returns the value of <me> (as a Real) by
|
|
-- replacement of <vars> by <vals>.

|
returns Real;
|
|
