Note: •
Pressing the ~
key during the
execution
of
a
matrix
calculation causes the
calculation to
be
suspended.
At
this
point,
the values of
matrixes
X, Y, and
M will be
retained
as those before the execution of the
calculation.
•
Press the n ~
[XI
in this
order
to perform the division of matrix
X
elements by scalar
n.
•
If most of the elements
of
a matrix have
the
same
value,
execute the n
[±]
operation with
all
the
matrix
elements
set
as 0 and then correct only the value
of each element having a
value
other
than
n.
This
will
facilitate the input
of
the
matrix
elements.
On
completion of the matrix
calculation,
the message "MATRIX OPERATI
O
N"
appears again
on the
display, indicating
that the
COMPUTER
is ready
for the next
matri
x
calculation. After the
determinant
value
of
matrix
Xis displ
a
yed by
pressing the
[]]key, the message "MATRIX

will
appear again if you
press one of
the
OJ,
OJ,~,
CE,~,
and
IENTERI
keys.
Example 2: To calculate X

Y,
using
the
values of the respective elements of
matrixes X and Y entered (stored
in
memory)
in Example 1
Key
Function
[BJ!)
M--+X:
Invokes the
memory
contents
of
matrix M into matrix X
(while clearing the previous
contents
of matrix X.)
[M±]
X
+
M
-->
M:
Adds the
value
of
matrix
X cumulatively to the
memory
contents of matrix
M.
To
perform
this
operation,
matrixes X and M must be equal to
each other in
both
the
number of
rows and the number of
columns.
