Conceptos básicos de diseño de algoritmos
Generar código a partir de algoritmos de MATLAB® permite diseñar, implementar y probar software en el área de trabajo de MATLAB. Puede hacer lo siguiente:
Verificar que sus algoritmos sean adecuados para la generación de código
Generar código C/C++ eficiente, legible y compacto automáticamente para eliminar la traducción manual y disminuir el riesgo de introducir errores en el código.
Modificar el diseño con código de MATLAB para tener en cuenta los requisitos específicos de las aplicaciones integradas y de escritorio, como la gestión del tipo de datos, el uso de la memoria y la velocidad.
Probar el código generado y verificar fácilmente que los algoritmos modificados sean funcionalmente equivalentes a sus algoritmos de MATLAB originales.
Generar funciones MEX para acelerar los algoritmos de MATLAB o el código de MATLAB de punto fijo.
Generar lenguaje de descripción de hardware (HDL) a partir de código de MATLAB.
