	For example, to change the element in the first row and
	second column of M5 to 728 and then display the
	resulting matrix:
	728
	AQ5
	R1o2
	E
	An attempt to store an
	element to a row or
	column beyond the size of the matrix results in re-sizing the
	matrix to allow the storage. Any intermediate cells will be
	filled with zeroes.
To send a matrix	You can send matrices between calculators just as you can
	send apps, programs, lists, and notes. See “Sharing data”
	on page 44 for instructions.

Matrix arithmetic

You can use the arithmetic functions (+, –, ×, ÷, and powers) with matrix arguments. Division left-multiplies by the inverse of the divisor. You can enter the matrices themselves or enter the names of stored matrix variables. The matrices can be real or complex.

For the next examples, store [[1,2],[3,4]] in M1 and [[5,6],[7,8]] in M2.
