freqdom.transpose {freqdom} | R Documentation |
For a given frequency-domain operator S
(freqdom
) the function freqdom.transpose
computes the transpose of S_\theta'
at
each frequency from the evaluation grid.
freqdom.transpose(x)
S |
a frequency-domain filter of type |
Let S = \{ S_\theta : \theta \in G \}
, where G
is some finite grid
of frequencies in [-\pi,\pi]
and S_\theta \in \mathbf{C}^{p \times p}
.
At each frequency \theta \in G
function freqdom.transpose
transposes
Resulting object is defined as
S' = \{ S_\theta': \theta \in G \}.
Function returns a frequency domain object (freqdom
) of dimensions L \times p_2 \times p_1
, where L
is the size of the grid.
The elements of the object correspond to S_\theta'
as defined above.
