` v=norm(a)`

` v=norm(a, n)`

Inputs | |

`a` |
Any vector or matrix. |

`n` |
A scalar specifying the type of norm to be computed. |

Outputs | |

`v` |
The computed norm. |

If

`a`

is a vector, `n`

can be any positive integer. If `n`

is `Inf`

, the
maximum of the absolute value of the elements of `a`

is returned.
If

`a`

is a matrix, `n`

can only be `1`

, `2`

or `inf`

, for computing, respectively,
the `1-norm`

, the `2-norm`

or `inf-norm`

of the input.
