Одним из самых эффективных методов знакомства со сложными математическими
системами является ознакомление со встроенными примерами их применения.
Система MATLAB содержит многие сотни таких примеров — практически по
примеру на каждый оператор или функцию. Наиболее поучительные примеры
можно найти в разделе demos, исполнив команду
» help demos
Ниже представлен выводимый этой командой список примеров:
