## LOWER Convert strings to lower case

Section: String Functions

### Usage

The `lower` function converts a string to lower case with the syntax

       y = lower(x)

where `x` is a string, in which case all of the upper case characters in `x` (defined as the range `'A'-'Z'`) are converted to lower case. Alternately, you can call `lower` with a cell array of strings

       y = lower(c)

in which case each string in the cell array is converted to lower case.

### Example

A simple example:

    --> lower('this Is Strange CAPitalizaTion')

    ans =

     this is strange capitalization

and a more complex example with a cell array of strings

    --> lower({'This','Is','Strange','CAPitalizaTion'})

    ans =

     ['this']   ['is']   ['strange']   ['capitalization']
