Иллюстрированный самоучитель по Matlab


Вызов списка демонстрационных примеров


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:
