13 DSP Blockset 4.1 Release Notes
13-12
Random Source Block
The Random Source block seed initialization better supports multiple copies of
the block in one Simulink model.
Also, the block no longer sets the seed of the MATLAB random number
generator function during block initialization.
Stack and Queue Blocks
The Stack and Queue blocks now correctly handle simultaneously triggered
control ports (such as the
Push and Pop ports).
Window Function Block
The Window Function block now errors out for non-floating-point inputs to
avoid possible segmentation violations.
