  "Description": "Some elementary matrix algebra tools are implemented to\nmanage block matrices or partitioned matrix, i.e. \"matrix of\nmatrices\" (http://en.wikipedia.org/wiki/Block_matrix). The\nblock matrix is here defined as a new S3 object. In this\npackage, some methods for \"matrix\" object are rewritten for\n\"blockmatrix\" object. New methods are implemented. This package\nwas created to solve equation systems with block matrices for\nthe analysis of environmental vector time series .\nBugs/comments/questions/collaboration of any kind are warmly\nwelcomed.",
