interpolation takes place). For single-channel signals, the Initial output
parameter value can be a vector of length M
o
or a scalar to repeat across the
M
o
elements of the initial output frames. For matrix outputs (M
o
-by-N or
M-by-N), the
Initial output parameter value can be a vector of length N to
repeat across all rows of the initial outputs, or a scalar to repeat across all
elements of the initial matrix outputs.
When the block has output all of the available signal samples, it can start again
at the beginning of the signal, or simply repeat the final value or generate zeros
until the end of the simulation. (The block does not extrapolate the imported
signal beyond the last sample.) The
Form output after final data value by
parameter controls this behavior:
•If
Setting To Zero is specified, the block generates zero-valued outputs for
the duration of the simulation after generating the last frame of the signal.
•If
Holding Final Value is specified, the block repeats the final sample for the
duration of the simulation after generating the last frame of the signal.
•If
Cyclic Repetition is specified, the block repeats the signal from the
beginning after generating the last frame. If there are not enough samples
at the end of the signal to fill the final frame, the block zero-pads the final
frame as necessary to ensure that the output for each cycle is identical
(e.g., the ith frame of one cycle contains the same samples as the ith frame
of any other cycle).
