Simulink® Release Notes

Change in Sample Time Behavior of Unary Minus Block

Release 14 changes the sample time behavior of the Unary Minus block. In Release 13, if the sample time of this block's input is continuous, the sample time of the block and its output is fixed in minor time step. this block is fixed in minor step and the output signal is fixed in minor step when the input is a continuos sample time signal. In Release 14, if the input is continuous, the block and output sample time are continuous also.

Initial Output of Conditionally Executed Subsystems

In previous releases, if the Initial output parameter of an Outport block in a conditionally executed subsystem specified [] as the initial output, the initial output of this port was the initial output of the block driving the Outport block. In this release, the initial output is undefined if the Initial output port specifies [].

Execution Context Default Changes

In R13 sp1 and DACORE2, execution contexts propagate across conditionally executed subsystem boundaries by default. In R14, execution context propagation does not cross a conditionally executed subsystem boundaries by default. You need to choose the Propagate execution context across subsystem boundary option in the subsystem's parameter dialog box.
