Counted Function (CountedFunction)

업데이트 날짜: 2023/1/15
Class to define functions in a way that facilitates counting the number of function calls/evaluations.
[fc,count] = CountedFunction.count_function_calls(f)
[fc,count] = CountedFunction.count_function_calls(f) takes a function handle,
f, and returns a function handle
fc and a counter function
fc performs the same function evaluation as
f (it is just wrapped around a
CountedFunction object which calls
f directly). Calling the counter function (i.e.
count()) will return the current number of function calls.
- For simple functions, such as
f = @(x) x^2, this can severely slow down function calls (by a factor of ~20).
- For complicated functions that have a long evaluation time to begin with, this performance hit is negligible.
See more examples in
% define the function f = @(x) x^2; % new function handle that counts the number of function evaluations [f,count] = CountedFunction.count_function_calls(f); % evaluates the function 1000 times for i = 1:1000 f(0); end % prints the number of function evaluations count()
ans = 1000
% evaluates the function another 1000 times for i = 1:1000 f(0); end % prints the number of function evaluations again count()
ans = 2000
