Integer Delay
5-244
The Initial conditions parameter specifies the output during the initial delay.
Both fixed and time-varying initial conditions can be specified. The initial
delay for a particular channel is the time elapsed from the start of the
simulation until the first input in that channel is propagated to the output.
Fixed Initial Conditions. The settings shown below specify fixed initial conditions.
The value entered in the
Initial conditions parameter is repeated at the
output for each sample time of the initial delay. A fixed initial condition in
frame-based mode can be one of the following:
•Scalar value to be repeated for all channels of the output at each sample time
of the initial delay. For a general M-by-N input with the parameter settings
below,
the first five samples in each of the N channels are zero. Note that if the
frame size is larger than the delay, all of these zeros are all included in the
first output from the block.
•Array of size 1-by-N-by-D. In this case, you can also specify different fixed
initial conditions for each channel. See the Array bullet in “Time-Varying
Initial Conditions” below for details.
Initial conditions cannot be specified by full matrices.
Time-Varying Initial Conditions. The following settings specify time-varying initial
conditions. For time-varying initial conditions, the values specified in the
Initial conditions parameter are output in sequence during the initial delay.
A time-varying initial condition in frame-based mode can be specified in the
following ways:
•Vector of length D, where each of the N channels have the same initial
conditions sequence specified in the vector. D is defined as follows:
- When an element of the delay entry is less than the frame size,
D = d + 1
where d is the maximum delay.
