Specify that a Dwork vector is used as a discrete state vector
int_T ssSetDWorkUsedAsDState(SimStruct *S, int_T vector, int_T usage)
SSimStruct representing an S-Function block.
vectorIndex of a Dwork vector, where the index is one of
0, 1, 2,
...
ssGetNumDWork(S)-1.
usageHow this vector is used. A value of 1 indicates
that the work vector is to be used to store the block's discrete states
(SS_DWORK_USED_AS_DSTATE), a value of
0 indicates that the work vector is to be used as
a work vector (SS_DWORK_USED_AS_DWORK).
0 if usage is SS_DWORK_USED_AS_DWORK
(0), otherwise returns 1.
Use in mdlInitializeSizes or
mdlSetWorkWidths to specify if the DWork vector
vector is used to store the block's discrete states,
SS_DWORK_USED_AS_DSTATE (1), or not,
SS_DWORK_USED_AS_DWORK (0), the
default.
Note
Specify the usage as SS_DWORK_USED_AS_DSTATE if the
following conditions are true. You want to use the vector to store discrete
states and you want the Simulink® engine to log the discrete states to the workspace at the end of a
simulation, if the user has selected the Save to
Workspace options on the Data Import/Export
pane of the Configuration Parameters dialog box.
