display last column in matrix with fprintf in matlab

To display the last column of a matrix using fprintf() in MATLAB, you can use indexing to extract the last column and then pass it to fprintf() for display. Here is an example:

main.m
% create a 3x3 matrix
A = magic(3);

% get the last column of the matrix
last_col = A(:,end);

% display the last column using fprintf
fprintf('%d\n', last_col);
162 chars
9 lines

In this example, we first create a 3x3 matrix using the magic() function. Then, we use indexing to extract the last column of the matrix by selecting all rows : and the last column end. We save this column to the variable last_col. Finally, we use fprintf() to display the column with a format specifier of %d, which specifies that the data is an integer. The \n adds a newline character at the end of each number so that they are displayed on separate lines.
