ssGetDiscStates

Arguments

Returns

A pointer (real_T *) to the discrete state vector as an array of length ssGetNumDiscStates(S). Returns NULL if the S-function does not have any discrete states.

Description

Use to obtain the block's discrete states. Typically, the state vector is initialized in mdlInitializeConditions, updated in mdlUpdate, and used in mdlOutputs. You can use this macro in the simulation loop, mdlInitializeConditions, or mdlStart routines.

Languages

C, C++

Examples

See the S-function dsfunc.c used in sfcndemo_dsfunc for an example on how to initialize and update the discrete state vector.
