Need help creating a matrix that updates based on input to a GUI

1 view (last 30 days)
I am creating a GUI that allows users to input 3 data points through edit text boxes. The user will then click a push button and the data will be added to a matrix.
Currently, the matrix is a 3 by 1 and every time the push button is clicked, the old data is erased and the new data replaces it.
I need to know how to have the matrix add a column each time new data is entered and the push button is clicked.
I tried using the "." after the matrix variable name and MATLAB didn't like it.
Can anyone help with this?

what if you did this:
matrix = [matrix; (button input)];
so m = [1 2 3] would go to
m = [1 2 3; 4 5 6]
with [4 5 6] as the input

just remember to clear the value before running things again.
m=[]; at initialization
