Buttons on the Matrix toolbar insert some of the Matrix-related operators. You can also type any operator using its keystroke. You may also wish to use the other summation operators to perform sums, or the vector and matrix-related functions.

To learn what a button does, hover the cursor over the button until a tooltip shows the title and a description appears on the message line of the Status Bar.
