You can initialize an empty array of a user-defined class. For example, theemptystatic method is a hidden method of theColorInRGBclass defined here. classdefColorInRGBpropertiesColor(1,3)= [1,0,0];endmethodsfunctionobj = ColorInRGB(c)ifnargin > 0 obj.Color = c;endendendend ...
215. Kth Largest Element in an Array 2019-12-13 09:21 −- O(NlogN)的时间复杂度+O(1)的空间复杂度 思路:先排序,然后输出第k大的元素即可,排序的时间复杂度是`O(NlogN)`,输出第k大元素的时间复杂度为`O(1)` ``` class Solution { public: int findKthLargest(vector& nums, ... ...
classdef ColorInRGB properties Color (1,3) = [1,0,0]; end methods function obj = ColorInRGB(c) if nargin > 0 obj.Color = c; end end end end Call the empty method. A = ColorInRGB.empty; You can expand this empty array into a nonempty array by assigning a value to it. For...
@james I am doing some calculations for example a=b+c. it is in the loop and c is changing. Sometimes c is "0×1 empty double column vector" and sometimes it is a reall number. When it is empty, I get error in a=b+c. That's why I need to make sure that if c is empty,...
