Detailed Description

A matrix with several copies of the same block on the diagonal.

This matrix implements an m by m block matrix. Each diagonal block consists of the same (non-block) matrix, while off-diagonal blocks are void.

One special application is a one by one block matrix, allowing to apply the vmult of the original matrix (or preconditioner) to a block vector.
