Detailed Description

template<typename Number>
class BlockSparseMatrixEZ< Number >

A block matrix consisting of blocks of type SparseMatrixEZ.

Like the other Block-objects, this matrix can be used like a SparseMatrixEZ, when it comes to access to entries. Then, there are functions for the multiplication with BlockVector and access to the individual blocks.
