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]
