Syntax
int_T *ssGetModeVector(SimStruct *S)
Arguments
S
SimStruct representing an S-function block.
Description
Returns a pointer (int_T *) to the mode vector.
This vector has length ssGetNumModes(S). Typically, this vector is initialized in mdlInitializeConditions if the default value of zero isn't acceptable. It is then used in mdlOutputs in conjunction with nonsampled zero crossings to determine when the output function should change mode. For example consider an absolute value function. When the input is negative, negate it to create a positive value, otherwise take no action. This function has two modes. The output function should be designed not to change modes during minor time steps. The mode vector may also be used in the mdlZeroCrossings routine to determine the current mode.
