Detailed Description

One dimensional S matrix.

By default, the application operator of this class uses the S matrix of the left subelement. If you want to used the S matrix of the right subelement, create a new S matrix with the modified copy constructor:

SMatrix1D left(...);
SMatrix1D right(left, true);

The new object right uses the data stored in left.

Constructor & Destructor Documentation

SMatrix1D() [1/2]

concepts::SMatrix1D::SMatrix1D	(	const ShapeFunction1D< Real > &	small,
		const ShapeFunction1D< Real > &	left,
		const ShapeFunction1D< Real > &	right
	)

Constructor.

The parameters are the shape functions of which the S matrix has to be computed. The shape functions have to be evaluated in the same mapped coordinates. Ie. small in -1, 0 and 1, left in -1, -0.5 and 0 and right in 0, 0.5 and 1. They have to be evaluated in the at least as many points as there are shape functions.

Parameters

small	The shape functions of one of the small elements.
left	The shape functions of the large element, restricted to the left subelement.
right	The shape functions of the large element, restricted to the right subelement.

SMatrix1D() [2/2]

concepts::SMatrix1D::SMatrix1D	(	const SMatrix1D &	s,
		const bool	flip = false
	)

Modified copy constructor.

This constructor can also be used to create an S matrix for the right subelement, see the description of the class for an example.

Parameters

s	S matrix to be copied (or the S matrix for the left subelement).
flip	By default set to false (ie. work as a copy constructor), if set to true, this creates an S matrix for the right subelement.

Member Data Documentation

data_

Array<Real> concepts::SMatrix1D::data_

private

Data of the S matrices.

The computation routine (in the constructor) computes the S matrices for the left and right subelement. This data is stored consecutively in this array.

If an S matrix is created using the copy constructor with flip set to true, this array is empty (and size set to 0) as all the data are already stored in the original S matrix.

Definition at line 133 of file smatrix.hh.

left_

Real* concepts::SMatrix1D::left_

private

Data for the S matrix of the left subelement.

This is just a pointer into the data_ array.

If an S matrix is created using the copy constructor with flip set to true, this is acctualy the S matrix of the right subelement and points to right_ of the original S matrix.

Definition at line 143 of file smatrix.hh.

n_

const uint concepts::SMatrix1D::n_

private

Size of the S matrices.

Definition at line 121 of file smatrix.hh.

right_

Real* concepts::SMatrix1D::right_

private

Data for the S matrix of the right subelement.

This is just a pointer into the data_ array.

If an S matrix is created using the copy constructor with flip set to true, this pointer is set to 0 as there is no 'right' subelement.
