在Matlab中将冒号作为函数的参数传递 [英] passing a colon as argument of a function in matlab

问题描述

我想知道是否可以使用冒号:" 作为函数的参数.

I would like to know if it's possible to use a colon ":" as argument of a function.

类似的东西:

function  y=func(x)
  if x is a colon
    do this
  else
    do that
  end

还可以将关键作品 end 作为函数的参数传递，也可以将 1:end ， 3:end-5 传递给函数>，等等. 我怀疑是否有可能，但我想确定.

Also is it possible to pass the key work end as argument of a function, and also 1:end, 3:end-5, etc... I doubt it's possible, but I would like to be sure.

此外，当我将"1:end"作为函数的参数传递时，我也会收到一个奇怪的错误，它不会产生任何错误，但是在函数内部，没有分配任何参数(甚至没有其他参数).有人知道会发生什么吗?

Also, I get a weird error when I pass "1:end" as argument of a function, it produces no error, but inside the function, no argument is assigned (not even the other arguments). Do someone know what happens?

推荐答案

您可以为自己的类覆盖这两者:

You can override both for your own classes:

classdef MyClass

properties(Access=public)
    data
end

methods
    function out = end(A,k,n)
         disp(A);
         disp(k);
         disp(n);
         out = [];
    end 

    function B = subsref(A,S)            
        disp(S);
        B = [];
    end
end
end

关于功能，我从未听说过这种功能.

As for functions, I never heard of such a functionality.
