• 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
• Use the E key to input "
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
• Use w to specify squaring, and 1w(
cubing. Note that you cannot use 6 for this input.
When you want to do this:
Select a matrix (MatA, MatB, MatC) and specify its
dimension
Select a matrix (MatA, MatB, MatC) and display its
data on the matrix editor screen
Input "MatA"
Input "MatB"
Input "MatC"
Input "MatAns"
Input the "det(" function for obtaining the determinant
Input the "Trn(" function for obtaining a transposed
