# entries -- get the entries of a matrix

- Usage:
    `entries M`
- Inputs:
  - M, a Matrix or a MutableMatrix
- Outputs:
  - a doubly nested List of the entries of M

## Description

    i1 : R = ZZ[x,y,z];

    i2 : M = matrix{{x,z,x*y},{x^2+z,y*z,1}}

    o2 = | x    z  xy |
         | x2+z yz 1  |

                 2      3
    o2 : Matrix R  <-- R

    i3 : entries M

                         2
    o3 = {{x, z, x*y}, {x  + z, y*z, 1}}

    o3 : List

    i4 : N = mutableMatrix{{x,z,x*y},{x^2+z,y*z,1}}

    o4 = | x    z  xy |
         | x2+z yz 1  |

    o4 : MutableMatrix

    i5 : entries N

                         2
    o5 = {{x, z, x*y}, {x  + z, y*z, 1}}

    o5 : List

## Ways to use entries:

- `entries(Matrix)`
- `entries(MutableMatrix)`
- entries(Vector) -- get the entries of a vector

## For the programmer

The object entries is a method function.
