add a column to a table in matlab

To add a column to a table in MATLAB, you can use the dot notation to access the table's variables and assign new values to them. Here's an example:

main.m
% Create a table
data = [1 2 3; 4 5 6; 7 8 9];
variableNames = {'Var1', 'Var2', 'Var3'};
t = table(data(:,1), data(:,2), data(:,3), 'VariableNames', variableNames);

% Add a new column
newColumn = [10; 11; 12];
t.NewColumn = newColumn;

% Display the updated table
disp(t)
273 chars
12 lines

In this example, we first create a table t with three columns named Var1, Var2, and Var3. Then, we create a new column NewColumn with three values [10; 11; 12] and assign it to t.NewColumn. Finally, we display the updated table using disp(t).

Make sure to replace data with your own data and variableNames with appropriate names for your table columns.

Remember that the number of elements in the new column must match the number of rows in the table.
