To combine two real matrices into a complex matrix
1. Select the Real-to-Complex command.
0 (M®
COMPLEX R^C
2. Enter or select the real matrix that will become the real part of the
complex matrix.
3. Enter or select the real matrix that will become the imaginary part of
the complex matrix.
This matrix must have the same dimensions as the matrix entered at
step 2.
4. Press (ITER).
The two real matrices are combined to form a complex matrix.
To split a complex matrix into two real matrices
1. Select tire Complex-to-Real conmrand.
0 (MTH) COMPLEX C^R
2. Enter or select the complex matrix that you want to split.
3. Press (ENTER).
The result is two real matrices formed from the complex matrix.
To conjugate each element of a complex matrix
1. Select the Conjugate function.
0 COMPLEX CONJ
2. Enter or select the complex matrix that you want to conjugate.
3. Press
TransForming complex matrices
To extract the matrix of real parts from a complex matrix
1. Select the Real Part function.
0 COMPLEX RE
2. Enter or select the complex matrix whose real components you want
to extract.
3. Press (ENTER).
The result is a matrix comprising just the real components of the
complex matrix.
