4. Optional: Press OS (new line) to start a new row in the
display.
5. Key in the rest of the matrix. You don’t need to add C ] delimiters
for subsequent rows—they’re added automatically later.
6 .
Press
( E N T E R ) .
To key in a wector using the command line:
1. Press ®o to begin the array. Because a vector is equivalent to a
single-column matrix, there is no need to group elements into rows
using additional delimiters unless you specifically want to create a
row-vector.
2. Key in the vector elements. Press
[ S P C
) to separate the elements.
3. Press
( E N T E R ) .
The HP 48 also provides special entry environments for algebraics
and arrays that use visually intuitive methods to key in these large
objects. See chapter 7, “The EquationWriter,” and chapter 8, “The
MatrixWriter,” for information.
Using the Command Line
The command line is essentially a workspace for keying in and editing
the objects you will enter into the HP 48. The command line appears
whenever you enter or edit text (except when you’re using the
EquationWriter application).
Accumulating Data in the Command Line
You can key any number of characters into the command line, using
up to half of the available memory. To enter more than one object in
the command line, use spaces, newlines (fr^(<—‘)), or delimiters to
separate objects. For example, you can key in 12
( S P C )
34 to enter two
numbers.
If you enter an P character outside of a string in the command
line, both the G character and the adjacent text are treated as a
“comment” and are stripped away when you press
( E N T E R ) .
When you type in the command line, characters are normally inserted
at the cursor position, and any trailing characters move to the
