	The second form is a shortcut for the combination of <code>MATRIXDEF</code> and <code>[[EQDEF]]</code>. It defines the symbol and creates an equation defining its value.		The second form is a shortcut for the combination of <code>MATRIXDEF</code> and <code>[[EQDEF]]</code>. It defines the symbol and creates an equation defining its value.

			Note that the matrix symbol is not identical with another symbol that has the same name but a different commutativity. To avoid confusion, always define your symbols as matrices before you use them for the first time.
