Writing S-Functions

ssSetNumContStates

Specify the number of continuous states that a block has.

C Syntax

• void ssSetNumContStates(SimStruct *S, int_T n)
  

Ada Syntax

• procedure ssSetNumContStates(S : in SimStruct; n : in Integer);
  

Arguments

S
   SimStruct representing an S-Function block.

n
   Number of continuous states to be set for the block represented by S.

Description

Use in mdlInitializeSizes to specify the number of continuous states as 0, a positive integer, or DYNAMICALLY_SIZED. If you specify DYNAMICALLY_SIZED, you can specify the true (positive integer) width in mdlSetWorkWidths; otherwise, the width used is the width of the signal passing through the block. If your S-function has continuous states, it needs to return the derivatives of the states in mdlDerivatives so that the solvers can integrate them. Continuous states are logged if the States option is selected on the Workspace I/O pane of the Simulation Parameters dialog box.
