Bloques que amplían la funcionalidad de Simulink con algoritmos personalizados, como MATLAB Function, C Function y S-Function

Utilice bloques de la biblioteca User-Defined Functions para ampliar la funcionalidad de modelado de Simulink^® mediante la creación de nuevos tipos de bloques. Puede implementar algoritmos de bloques utilizando código de MATLAB^®, C/C++ y Fortran^®. Utilice estos bloques cuando los bloques integrados no ofrezcan el cálculo específico o el comportamiento de sistema que necesita.

Para añadir bloques de esta biblioteca al modelo, consulte Add Blocks to Models.

Working with the Reinitialize Function Block

Use a Reinitialize Function block to reset the initial condition of a Discrete-Time Integrator block for every function-call event received by a subsystem. In this example, the Reinitialize Function block is inside a subsystem, and the subsystem receives a function-call event at every five simulation time steps.
