Multiplying Complex Matrices
The product of two complex matrices can be calculated by using the fact
that (
YX
)
P
=
P
.
To calculate
YX
, where
Y
and
X
are complex matrices:
1. Store the elements of
Y
and
X
in memory, in the form either of
Z
P
or
Z
C
.
2. Recall the descriptor of the matrix representing
Y
into the
display.
3. If the elements of
Y
were entered in the form of
Y
C
, press
´p
to transform
Y
C
into
Y
P
.
4. Press
´>
2 to transform
Y
P
into
.
5. Recall the descriptor of the matrix representing
X
into the
display.
6. If the elements of
X
were entered in the form
X
C
, press
´p
to transform
X
C
into
X
P
.
7. Designate the result matrix; it must not be the same matrix as
either of the other two.
