# trimZeros

Create a tight bounding box by removing zeros.

## Syntax

    data = trimZeros(data)
    [data, ind] = trimZeros(data)

## Description

`trimZeros` reduces the size of a matrix to create a tight bounding box around the data by removing zeros. For example, in 2D, if the input data is given by

        0 0 0 0 0 0
        0 0 0 3 0 0
        0 0 1 3 4 0
        0 0 1 3 4 0
        0 0 1 3 0 0
        0 0 0 0 0 0

`trimZeros` will return

        0 3 0
        1 3 4
        1 3 4
        1 3 0

## Inputs

`data` | matrix to trim

## Outputs

`data` | trimmed matrix
`ind` | indices used to trim matrix
