The Complex Transformations Between Z
P
and Z
An additional transformation must be done when you want to calculate the
product of two complex matrices, and still another when you want to
calculate the inverse of a complex matrix. These transformations convert
between the
Z
P
representation of an
m×n
complex matrix and a
2m×2n
partitioned matrix of the following form:
X
Y
Y
X
Z
.
The matrix
created by the
>
2 transformation has twice as many
elements as
Z
P
.
For example, the matrices below show how
is related to

or
into
the display, then press the keys shown above. The transformation is done to
the specified matrix; the result matrix is not affected.
