how to combine 6 different data sets which are in the table format into 1 large table if they have different rows and columns in matlab

To combine multiple tables with different rows and columns into one large table in MATLAB, you can use the outerjoin function from the MATLAB Statistics and Machine Learning Toolbox. This function performs an outer join operation, which combines the tables based on common variables while preserving all rows and columns from all tables.

Here is an example of how you can combine six different tables into one using the outerjoin function:

main.m
% Sample data for six different tables
table1 = table([1; 2; 3], {'A'; 'B'; 'C'}, 'VariableNames', {'ID', 'Name'});
table2 = table([4; 5], {'D'; 'E'}, [10; 20], 'VariableNames', {'ID', 'Name', 'Value'});
table3 = table([1; 3], [100; 300], 'VariableNames', {'ID', 'Price'});
table4 = table([2; 4], [200; 400], 'VariableNames', {'ID', 'Price'});
table5 = table([5; 6], [500; 600], 'VariableNames', {'ID', 'Price'});
table6 = table([1; 3; 5], [0.1; 0.3; 0.5], 'VariableNames', {'ID', 'Rate'});

% Combine tables using outerjoin
combinedTable = outerjoin(table1, table2, 'Type', 'full');
combinedTable = outerjoin(combinedTable, table3, 'Type', 'full');
combinedTable = outerjoin(combinedTable, table4, 'Type', 'full');
combinedTable = outerjoin(combinedTable, table5, 'Type', 'full');
combinedTable = outerjoin(combinedTable, table6, 'Type', 'full');

% Display the combined table
disp(combinedTable);

In this example, we have six different tables (table1, table2, table3, table4, table5, table6) with various columns and rows. We use the outerjoin function to combine these tables one by one, specifying the 'full' type for the join operation to include all rows and columns. The final result is stored in the combinedTable variable.

Note that you may need to adjust the join type ('Type') according to your requirements. The 'full' join type ensures that all rows and columns from all tables are preserved. You can also use other join types such as 'inner', 'left', or 'right' join, depending on your desired output.
