	data in Matrix
Appendix
<#096> Input MatA =		2		1		, MatC =		1	0	–1	.
			1	1				0	–1	1
<#097> Copy MatA =		2		1		to MatB and edit the contents
			1	1
of MatB to MatB =				2		–1	.

•The following examples use the matrices input in Examples <#096> and <#097> (MatA, MatB, MatC).

<#098> MatA + MatB (Adding Two Matrices)

<#099> MatA ⋅ MatB, MatB ⋅ MatA – MatA ⋅ MatB (Multiplying Two Matrices)

<#100> 3 ⋅ MatA (Matrix Scalar Multiplication)

<#101> Obtain the determinant of Matrix A (det(MatA)). <#102> Obtain the transposition of Matrix C (Trn(MatC)). <#103> Obtain the inverse matrix of Matrix A (MatA–1).

• Use the Ekey to input “–1”. Note that you cannot use 6for this input.

<#104> Obtain the absolute value (Abs(MatB)) of each element of Matrix B.

• Use 1w(Abs).

<#105> Determine the square (MatA2) or cube (MatA3) of Matrix A.

•Use wto specify squaring, and 1w(x3) to specify cubing. Note that you cannot use 6for this input.
