connect two tables in matlab

In Matlab, you can combine tables by using the join function. The join function accepts four arguments: two tables, a key variable, and the type of join. The key variable is used to link the two tables based on the common column in both tables.

Here is an example code snippet to join two tables:

main.m
% Create two tables to join
T1 = table({'Male';'Female';'Male';'Female'}, [38;43;40;49], [71;69;64;64], 'VariableNames',{'Gender' 'Age' 'Height'});
T2 = table({'Male';'Female'}, {'Runner';'Swimmer'}, 'VariableNames',{'Gender' 'Sport'});

% Join the two tables using 'Gender' column as a key variable
T3 = join(T1, T2, 'Keys','Gender')

% Output the result
disp(T3)
365 chars
10 lines

The output T3 will be a new table with columns from both tables combined based on the Gender column. The Keys argument is used to specify which column(s) to use as the key variable for joining. The default type of join is an inner join, which means only the rows with matching keys in both tables will be included in the output.

Note that in order to use the join function, both tables need to have at least one column with the same name as a key variable.
