### Description

Get band matrix from ContactGroup.

### Usage

    getBandMatrix(cg, band.no=1)

### Arguments

`band.no` | Integer specifying which matrix band. `band.no` = 1 retrieves the main diagonal.

### Details

A band matrix is a matrix whose columns are the `band.no`-th off-diagonal of each sample's contact matrix. If there are `k` samples and matrix band `band.no` has `r` entries, then the returned band matrix is of dimension `r` x `k`.

### Value

A matrix with one column per sample in the ContactGroup and number of rows equal to the length of the matrix band.
