MATLAB end

The end keyword in MATLAB serves two main purposes:

It terminates a block of code.
It indicates the last array index.

MATLAB end syntax:

Example: Use end keyword to terminate the block of code:

a = ones(4)
for k = 1:length(a)
    if a(k) == 1
        a(k) = 0;
    end
end
disp('......')
disp(a)
disp('...end')

Output:

a = 4�4
     1     1     1     1
     1     1     1     1
     1     1     1     1
     1     1     1     1
......
     0     1     1     1
     0     1     1     1
     0     1     1     1
     0     1     1     1
...end

Example: Use end keyword to indicate last array index:

a = randi(100,4,4)
b = a(end,2:end) % here first end argument indicates the last row, 
%and the second  indicates the columns number from 2 to the last
a = 4�4
    43    66    68    66
    92     4    76    18
    80    85    75    71
    96    94    40     4
b = 1�3
    94    40     4
