HP HP-28S - Keying in a Matrix; Viewing a Large Matrix

The calculations you performed on vectors also apply to matrices
(with the exception of the dot and cross products). You can multiply
or divide a matrix by a number, and you can add or subtract two
matrices (provided that the matrices have the same dimensions).
Keying In a Matrix
Key in the following matrix:
Start the matrix.
rn
Enter each row of the matrix like a separate vector.
~~~~~~~----------,
rn 1,2,3 1: [[ 1 2 3 ]
rn
[ 133 ]
[ 1,3,3 [ 1 2 4 ]]
rn 1,2,4 I ENTER I tBaDDllnJIlllBlmImmIm
Viewing a Large Matrix
When a matrix has many elements or non-integer elements, you may
not see the entire matrix at once. To view a large matrix, use .1 EDIT I
(if the matrix is in level 1) or .1 VISIT I to return the matrix to the com-
mand line. You can then use the cursor menu keys to display any part
of the matrix. For details, refer to HEditing Existing Objects
