MATLAB

Thus far you know several kinds of containers available in MATLAB: vectors, matrices, cell arrays, and structs. In many other languages, a container has a unique set of methods available to each object of the class. You are to create a vector class that operates closely to the vector container in C++.

Create a vector value class with two private properties: Contents and Size.

Implement the following methods:

Vector Constructor - initialize Contents to empty vector and set the Size to 0

push_back(value) - takes number and pushes it into the vector at the end, increases size by 1

pop_back() - takes no input, removes the element at the end of the vector, decreases size by 1

at(index) - takes an integer as index, returns the value at that index. For example: vec.at(2) returns the 2nd element

size() - takes no input, returns the current size of the vector

empty() - takes no input, returns logical true or false if the vector is empty

insert(index, value) - replaces value at index in Contents vector.

Follow all instructions carefully to ensure you understand what each method does.

SOLUTION **THIS IS JUST AN OUTLINE THAT NEEDS TO BE FILLED IN**

classdef Vector
    properties
        % implement Contents and Size props
    end
    methods
        % Constructor
        function vector = Vector()
      
        end
        % push_back
      
        % pop_back
      
        % at
      
        % size
      
        % empty
      
        % insert
    end
end

Explanation / Answer

classdef Vector
properties
% implement Contents and Size props
content
size
end
methods
% Constructor
function vector = Vector()
content=[]
size=0
end
% push_back
function p=push_back(a)
size=size+1
content(size)=a
end
% pop_back
function q=pop_back(b)
p=content(size)
size=size-1
end
% at
function r=at(ind)
r=content(ind)
end
% size
function s=get_size()
s=size
end
% empty
function emp=check_empty()
if size==0
emp=true
else
emp=false
end
end
% insert
function ins=insert(ind,val)
contents(ind)=val
end
end
end
