ssIsVariableStepSolver - Determine if a variable-step solver is being used to solve the S-function

Syntax

boolean_T ssIsVariableStepSolver(SimStruct *S)

Arguments

S

SimStruct representing an S-Function block or a Simulink model.

Returns

The Boolean value true if the solver being used to solve S is a variable-step solver. Otherwise, returns false.

Description

Use to determine if the simulation is being solved using a variable or fixed-step solver. This is useful when you are creating S-functions that have zero crossings and an inherited sample time.

Languages

C, C++

Example

See the S-function vsfunc.c used in sfcndemo_vsfunc.mdl and the S-function sfun_atol.c used in sfcndemo_sfun_atol.mdl.
