ssSetNumDiscStates

Specify the number of discrete states that a block has

Syntax

void ssSetNumDiscStates(SimStruct *S, int_T nDiscStates)

Arguments

S

SimStruct representing an S-Function block.

nDiscStates

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

Description

Use in mdlInitializeSizes to specify the number of discrete 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 discrete states, it should return the next discrete state (in place) in mdlUpdate. Discrete states are logged if the States option is selected on the Data Import/Export page of the Configuration Parameters dialog box.

Languages

C, C++

Example

See the S-function dsfunc.c used in sfcndemo_dsfunc.
