Section: String Functions
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.
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]
