remove final row and column from matrix in matlab

To remove the final row and column from a matrix in MATLAB, you can use indexing and slicing. Here is an example code that demonstrates this:

main.m
% create a sample matrix
M = magic(4);

% remove the final row and column
M = M(1:end-1, 1:end-1);

% display the updated matrix
disp(M);

In this code, we first create a sample matrix M using the magic function. To remove the final row and column from this matrix, we use indexing and slicing. The expression M(1:end-1, 1:end-1) selects all rows and columns except the last one, effectively removing the final row and column. We then assign the updated matrix to M. Finally, we display the updated matrix using the disp function.
