Description

[ S3 method for blockmatrix object

Usage

## S3 method for class 'blockmatrix'
 M[i = 1:nrow(M), j = 1:ncol(M),numeric_value=TRUE,blockmatrix=FALSE,...]

Arguments

M	a blockmatrix object
i,j	matrix indices (numerical or character)
numeric_value	logical value . If TRUE (Default if i,j have both length 1) and i,j have both length 1, a i,j numeric matrix is returened.
blockmatrix	logical value. If TRUE (Default if i or j have length greater than 1) a blockmatrix is returned.
...	further argument for [ method

Value

The i,j matrix as a numarical matrix if blockmatrix is FALSE, otherwise the returen oblect is a blockmatrix object. In case i is a character vector, the method returns a list of objects with name containing in i and taken from M.
