Detailed Description

template<class F, int dim>
class concepts::TColumnBlock< F, dim >

A column of a T matrix.

More than one T column are arranged in a linked list. These columns are inserted into the T matrix.

This T column can be used for 2 and 3 dimensional problems where the T column needs to have a block form (ie. for the application of an S matrix). Each block represents one vector component.

It is assumed that the T matrices have a multiindex.

The first /c dim indices are used for the tensorised shape functions. The range of the first indices could be different in the different blocks. E.g. that is used with edge elements (e.g. hp2Dedge::Quad).

The last index is used for the block structure. The number of blocks is equal to the dimension of elements /c dim.

I.e. the T matrix of tensorised shape functions in 2 dimensions has a threefold multiindex.

The appropiate S matrix is SMatrixBlock

Parameters:

n	An array of size (/c dim^2) with the range of the multiindices, e.g. /c dim=2, /c n = {2, 3, 3, 2} builds two blocks of with the particular ranges of the multiindex (0..1,0..2,0) and (0..2,0..1,1)
idx	Index of the column in a T matrix
lnk	Pointer to the next column (linked list)
