Integer Delay

5-245

- When the all elements of the delay entry are greater than the input frame

size,

D = d + input frame size - 1

Only the first d entries of the initial condition vector will be used; the rest of

the values are ignored, but you must include them nonetheless. For a

two-channel ramp input

[1:100; 1:100]' with a frame size of 4 and the

parameter settings below,

the block outputs the following sequence of frames at the start of the

simulation.

Note that since one of the delays, 2, is less than the frame size of the input,

4, the length of the

Initial conditions vector is the sum of the maximum

delay and 1 (5+1), which is 6. The first five entries of the initial conditions

vector are used by the channel with the maximum delay, and the rest of the

entries are ignored. Since the first channel is delayed for less than the

maximum delay (2 sample time units), it only makes use of two of the initial

condition entries.

•Array of size 1-by-N-by-D, where D is defined in the Vector bullet above in

“Time-Varying Initial Conditions” on page 5-244. In this case, the kth entry

of each 1-by-N entry in the array corresponds to an initial condition for the

kth channel of the input matrix. Thus, a 1-by-N-by-D initial conditions input

allows you to specify different initial conditions for each channel. For

instance, for a two-channel ramp input

[1:100; 1:100]' with a frame size

of 4 and the parameter settings below,
