genvarname
2genvarname
Purpose Construct valid variable name from string
Syntax varname = genvarname(str)
varname = genvarname(str, exclusions)
Description varname = genvarname(str) constructs a string varname that is similar to or
the same as the str input, and can be used as a valid variable name. str can
be a single character array or a cell array of strings. If str is a cell array of
strings, genvarname returns a cell array of strings in varname. The strings in a
cell array returned by genvarname are guaranteed to be different from each
other.

varname = genvarname(str, exclusions) returns a valid variable name that
is different from any name listed in the exclusions input. The exclusions
input can be a single character array or a cell array of strings. Specify the
string 'who' for exclusions to create a variable name that will be unique in the
current MATLAB workapace (see “Example 4”, below).
Note genvarname returns a string that can be used as a variable name. It
does not create a variable in the MATLAB workspace. You cannot, therefore,
assign a value to the output of genvarname.
Remarks A valid MATLAB variable name is a character string of letters, digits, and
underscores, such that the first character is a letter, and the length of the
string is less than or equal to the value returned by the namelengthmax
function. Any string that excedes namelengthmax is truncated in the varname
output. See “Example 6”, below.
The variable name returned by genvarname is not guaranteed to be different
from other variable names currently in the MATLAB workspace unless you use
the exclusions input in the manner shown in “Example 4”, below.
If you use genvarname to generate a field name for a structure, MATLAB does
create a variable for the structure and field in the MATLAB workspace. See
“Example 3”, below.
