Creating an anonymous function and calling it passing arguments in one line in MATLAB

Question

You can do in matlab something like this:

>> fh = @(x) x^2
fh = 
   @(x)x^2

and then

>> fh(3)
ans =
    9

Now I look for a way to create the anonymous function and call it in one line, like this (it does not work):

@(x) x^2 (3) <-- This code does not work!

Is there a way to do it?

Answer 1

feval( @(x) x^2, 3)是你需要的。

Answer 2

这可以工作（它也适用于矩阵）：

arrayfun(@(x) x^2,3)
