Section 12: Calculating with Matrices
Matrix A now represents the complex matrix Z in Z
The Complex Transformations Between 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
P
between the Z
partitioned matrix of the following form:
created by the > 2 transformation has twice as many
The matrix

elements as Z
.
For example, the matrices below show how
The transformations that convert the representation of a complex matrix
P
between Z
and
To do either of these transformations, recall the descriptor of Z
the display, then press the keys shown above. The transformation is done to
the specified matrix; the result matrix is not affected.
