genvarname
(To be removed) Construct valid variable name from string
genvarname
will be removed in a future release. Use matlab.lang.makeValidName
and matlab.lang.makeUniqueStrings
instead.
Description
varname = genvarname(
constructs a string or character vector str
)varname
that is similar
to or the same as the str
input, and can be used as a valid
variable name. If str
is a string array or cell array of
character vectors, genvarname
returns a string array or cell
array of character vectors in varname
. The elements returned by
genvarname
are guaranteed to be different from each
other.
Note
genvarname
does not create a variable in the
MATLAB® workspace. You cannot, therefore, assign a value to the output
of genvarname
.
varname = genvarname(
returns a valid variable name that is different from any name listed in the
str
,exclusions
)exclusions
input.
Specify the function who
in
exclusions
to create a variable name that will be unique in
the current MATLAB workspace.
Examples
Input Arguments
Tips
A valid MATLAB variable name consists of letters, digits, and underscores, such that the first character is a letter, and the length of the name is less than or equal to the value returned by the
namelengthmax
function. Any name that exceedsnamelengthmax
is truncated in thevarname
output.If the
str
input contains any white-space characters,genvarname
removes them and capitalizes the next alphabetic character instr
. Ifstr
contains any nonalphanumeric characters,genvarname
translates these characters into their hexadecimal value.
