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

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

I think this will work, I just need to move some things around. Thanks for your help!!!

just remember to clear the value before running things again.

m=[]; at initialization
