Specify the sizes of the work vectors and create the run-time parameters required by this MATLAB S-function
Simulink.MSFcnRunTimeBlockclass representing the Level-2 MATLAB S-Function block.
The Simulink® engine calls this optional method to enable this S-function to set the sizes of state and work vectors that it needs to store global data and to create run-time parameters (see Create and Update S-Function Run-Time Parameters). The engine invokes this method after it has determined the input port width, output port width, and sample times of the S-function. This allows the S-function to size the state and work vectors based on the number and sizes of inputs and outputs and/or the number of sample times.
A Level-2 MATLAB S-function must implement this method if any
DWork vectors are used in the S-function. In the case of MATLAB S-functions,
this method sets the number of DWork vectors and initializes their
attributes. For example, the following code in the
specifies the usage for the first DWork vector:
s.DWork(1).Usage = type;
s is an instance of the
Simulink.MSFcnRunTimeBlock class representing
the Level-2 MATLAB S-Function block and
one of the following:
