• 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
Tw o 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 E key to input “
–1
”. Note that you cannot use
6 for this input.
<#104> Obtain the absolute value (Abs(MatB)) of each element of
Matrix B.
•Use 1w(Abs).
<#105> Determine the square (MatA
2
) or cube (MatA
3
) of Matrix A.
•Use w to specify squaring, and 1w(x
3
) to specify
cubing. Note that you cannot use 6 for this input.
