display last column in matrix in matlab

To display the last column of a matrix in MATLAB, you can use indexing by specifying the colon sign ":" as the row index and the end keyword as the column index. Here's an example:

main.m
% create a sample matrix
A = [1 2 3; 4 5 6; 7 8 9];

% display the last column of the matrix
last_column = A(:, end)
117 chars
6 lines

This will output:

main.m
last_column =

   3
   6
   9
30 chars
6 lines

Here, the : specifies that all rows should be selected, while the end keyword specifies the last column of the matrix. The resulting column vector is then assigned to the variable last_column.
