ssSetDWorkUsedAsDState (Writing S-Functions)

Specify that a data type work vector is used as a discrete state vector.

Syntax

void ssSetDWorkUsedAsDState(SimStruct *S, int_T vector, 
int_T usage)

Arguments
S
SimStruct representing an S-function block.

vector
Index of a data type work vector, where the index is one of 0, 1, 2, ... ssGetNumDWork(S)

Usage
How this vector is used

Description

Use in mdlInitializeSizes or mdlSetWorkWidths to specify the usage of the specified work vector, either SS_DWORK_USED_AS_DSTATE (used to store the block's discrete states) or SS_DWORK_USED_AS_DWORK (used as a work vector, 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 and you want Simulink to log the discrete states to the workspace at the end of a simulation, if the user has selected the Save to Workspace option on Simulink's Simulation Parameters dialog.
