index the last 5 rows of a table in matlab

To index the last 5 rows of a table in MATLAB, you can use the end keyword and the colon operator, as follows:

main.m
% create a sample table
T = table([1;2;3;4;5;6;7;8;9;10]', rand(10,1), 'VariableNames', {'ID', 'Value'});

% index the last 5 rows of the table
last_rows = T(end-4:end,:);
172 chars
6 lines

In this example, the variable T represents the table of interest. The end keyword refers to the last element of the table, and the colon operator : is used to specify a range of rows. The end-4 index calculates the fifth row from the end, so the range [end-4:end] corresponds to the last 5 rows of the table. Finally, the variable last_rows stores the indexed subset of the table.
