2func2str
Purpose Construct a function name string from a function handle
Syntax s = func2str(fhandle)
func2str
Description func2str(fhandle) constructs a string s that holds the name of the function
to which the function handle fhandle belongs.
When you need to perform a string operation, such as compare or display, on a
function handle, you can use func2str to construct a string bearing the
function name.
The func2str command does not operate on nonscalar function handles.
Passing a nonscalar function handle to func2str results in an error.
Examples Example 1
Convert a sin function handle to a string:
fhandle = @sin;
func2str(fhandle)
ans =
sin
Example 2
The catcherr function shown here accepts function handle and data
arguments and attempts to evaluate the function through its handle. If the
function fails to execute, catcherr uses sprintf to display an error message
giving the name of the failing function. The function name must be a string for
sprintf to display it. The code derives the function name from the function
handle using func2str:
function catcherr(func, data)
try
ans = func(data);
disp('Answer is:');
ans
catch
disp(sprintf('Error executing function ''%s''\n', ...
func2str(func)))
end
