Anyone here know how to edit data in a matlab 2D array (table).
I created a table using the xlsread command but now i want to write a function that can edit that array. I want to do this in simulink but can't seem to find a block that can do this.

Thanks for the useless answers.
I figured it out, there are two ways to edit a table. You can use embedded matlab function like this:
function y = WriteToArray(u,row,column,replacement); %#eml; u(row,column) = replacement; y = u;
or you can simply use the Assignment Block.

1) Build a GUI, you could just use guide, drag one uitable inside of the GUI, a button to load data and another to save data. MATLAB Basics: Adding a table to a GUI
2) In simulink place an annotation (double click on the background and write something), now press on it with the mouse right button and go to annotation properties, now just put the name of the GUI in ClickFcn, now when you want to edit the array just click on that annotation.

I need to be able to edit the table (2d array) in simulink because this application will essentially end up in an embedded target. So i need to programmatically edit the table in simulink.

I'm assuming that by "edit", you really mean "manipulate". If you've read the data from Excel into a MATLAB workspace variable, you can load it into Simulink using a Constant block and enter the matrix variable name for value.
