class Tensor from GeomFill
---Purpose: used to store the "gradient of gradient"
uses
Array1OfReal from TColStd,
Vector from math,
Matrix from math
raises DimensionError from Standard,
RangeError from Standard
is
Create(NbRow, NbCol, NbMat : Integer)
returns Tensor;
Init(me : in out; InitialValue: Real)
---Purpose:Initialize all the elements of a Tensor to InitialValue.
is static;
Value(me; Row, Col, Mat: Integer)
---Purpose: accesses (in read or write mode) the value of index <Row>,
-- <Col> and <Mat> of a Tensor.
-- An exception is raised if <Row>, <Col> or <Mat> are not
-- in the correct range.
---C++: alias operator()
---C++: return const &
---C++: inline
returns Real
is static;
ChangeValue(me : in out; Row, Col, Mat: Integer)
---Purpose: accesses (in read or write mode) the value of index <Row>,

-- An exception is raised if <Row>, <Col> or <Mat> are not
-- in the correct range.
---C++: alias operator()
