Matrices
In addition to those in the Matrix MATH menu, the following
matrix operations are allowed. Dimensions must be correct:
• matrix + matrix
• matrix – matrix
• matrix × matrix
• Scalar multiplication (for example, 2 × matrix)
• matrix × vector (vector will be interpreted as a column
vector)
% t NAMES
% t displays the matrix NAMES menu, which shows
the dimensions of the matrices and lets you use them in
calculations.
% t MATH
% t " displays the matrix MATH menu, which lets
you perform the following operations:
% t EDIT
% t ! displays the matrix EDIT menu, which lets
you define or edit matrix [A], [B], or [C].
1: [A] Definable matrix A
2: [B] Definable matrix B
3: [C] Definable matrix C
4: [Ans] Last matrix result (displayed as [Ans]=m×n) or
last vector result (displayed as [Ans] dim=n). Not
editable.
5: [I2] 2×2 identity matrix (not editable)
6: [I3] 3×3 identity matrix (not editable)
