combine two different tables to one in matlab

You can combine two different tables into one using the join function in MATLAB. The join function requires a common variable to merge the tables on.

Here is an example of how to combine two tables ("table1" and "table2") into one new table ("combinedTable") using the join function:

main.m
% create two sample tables
table1 = table([1; 2; 3], {'a'; 'b'; 'c'}, 'VariableNames', {'ID', 'Name'});
table2 = table([1; 2; 4], [10; 20; 30], 'VariableNames', {'ID', 'Value'});

% join tables on the common variable "ID"
combinedTable = join(table1, table2, 'Keys', 'ID');

In this example, the common variable "ID" is used to merge the two tables. The resulting "combinedTable" has all the columns from both "table1" and "table2". If there are rows with matching values in the "ID" column in both tables, the columns from each table will be combined into one row in the combined table. If there are unmatched values in either table, the corresponding columns in the combined table will have missing values (NaN).
