Uses of Function handles:
The Function handles can also be generated for functions other than anonymous functions, both built-in & user-defined functions. For illustration, the below would generate a function handle for the built-in factorial function:
>> facth = @factorial;
The @ operator acquiires the handle of the function, that is then stored in a variable facth.
The handle can be used to call the function, merely like the handle for the anonymous functions, for illustration:
>> facth(5)
ans =
120
By using the function handle to call the function rather than of using the name of the function does not itself elaborate why this is helpful, so a clear question would be why the function handles are essential.
str2num function - String: The function str2num does the opposite; it takes the string in which a number is stored and converts it to the type double: >> num = str2num('123.
