Section: String Functions
upper function converts a string to upper case with
the syntax
y = upper(x)
where x is a string, in which case all of the lower case
characters in x (defined as the range 'a'-'z') are
converted to upper case. Alternately, you can call upper
with a cell array of strings
y = upper(c)
in which case each string in the cell array is converted to upper case.
--> upper('this Is Strange CAPitalizaTion')
ans =
THIS IS STRANGE CAPITALIZATION
and a more complex example with a cell array of strings
--> upper({'This','Is','Strange','CAPitalizaTion'})
ans =
[THIS] [IS] [STRANGE] [CAPITALIZATION]
