ssGetAbsTol (Writing S-Functions)

Get the absolute tolerances used by the model's variable step solver.

Syntax

real_T *ssGetAbsTol(SimStruct *S)

Arguments
S
SimStruct representing an S-function block.

Description

Use in mdlStart to get the absolute tolerances used by the variable step solver for this simulation. Returns a pointer to an array that contains the tolerance for each continuous state.

Note Absolute tolerances are not allocated for fixed step solvers. Therefore, you should not invoke this macro until you have verified that the simulation is using a variable step solver, using ssIsVariableStepSolver.

Languages

C, C++

Example

{
    int isVarSolver = ssIsVariableStepSolver(S);

    if (isVarSolver) {
        real_T *absTol = ssGetAbsTol(S);
        int    nCStates = ssGetNumContStates(S);

        absTol[0] = whatever_value;
        ...
        absTol[nCStates-1] = whatever_value;
    }
}
