Get a block's floating-point work vector
real_T *ssGetRWork(SimStruct *S)
Use to access the floating-point work vector used by the block represented by S. The vector consists of elements of type real_T and is of length ssGetNumRWork(S). Typically, this vector is initialized in mdlStart or mdlInitializeConditions, updated in mdlUpdate, and used in mdlOutputs. You can use this macro in the simulation loop, mdlInitializeConditions, or mdlStart routines.
