Unidades en Simulink
Simulink permite especificar unidades físicas como atributos de señales en los límites de los componentes del modelo. Especificar, controlar y visualizar las unidades de señales permite garantizar la congruencia de los cálculos en los distintos componentes de modelo. Por ejemplo, este grado adicional de comprobación de congruencia puede ser útil si se están integrando muchos componentes desarrollados por separado en un modelo de sistema global de gran tamaño. Para empezar con las unidades, consulte Unit Specification in Simulink Models.
