Conversión manual a punto fijo en MATLAB

Conversión asistida de algoritmos de punto flotante a algoritmos de punto fijo

Utilice la función buildInstrumentedMex para instrumentar un algoritmo y registrar los valores mínimos y máximos de todas las variables con nombre e intermedias. Utilice la función showInstrumentationResults para proponer tipos de datos de punto fijo basados en estos valores registrados.
