Detailed Description

A block in a covariance matrix.

A block in a covariance matrix represents a correlation between two retrieval quantities. Each block holds a pointer to either a dense matrix of type Matrix or type Sparse. In addition to this it holds to two block indices i and j and two range objects that describe the position of the block in terms of the rows and columns of blocks in the matrix and the row and columns of elements, respectively.
