The HatrixWriter
The HP 48’s MatrixWriter application provides you with
extensive capabilities for entering and manipulating arrays (both
one-dimensional matrices and two-dimensional matrices).
How the HP 48 Displays Arrays
The stack displays arrays as numbers within nested
L J
delimiters. A
pair of C
J
delimiters enclose the entire array, and additional pairs
enclose each row within the matrix. For example, here’s a 3 x 3
matrix as it might appear on the stack:
Vectors (also called column vectors or one-column matrices) appear on
the stack as numbers within a single level of [ ] delimiters:
C 2 4 6 8 ]
Row vectors (one-rote matrices) appear on the stack as numbers
within tvjo pairs of [ j delimiters:
In addition, the current coordinate mode and angle mode affect
how 2-dimensional and 3-dimensional vectors are displayed. See
“Displaying 2D and 3D Vectors” on page 13-1 for details.
