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:
.
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 Z

The transformations that convert the representation of a complex matrix
between Z

and
are shown in the following table.
To do either of these transformations, recall the descriptor of Z
P
or
into
the display, then press the keys shown above. The transformation is done to
the specified matrix; the result matrix is not affected.
