あなたの模型(Model)は離散(digital)ですか連続(analog)ですか

Last updated at Posted at 2020-09-14

<この項は書きかけです。順次追記します。>

Portable C Compilerの作者が、
MatlabのMathworksで仕事をしたことを知った。

C Compilerは離散で、Matlabは連続。

MBSD(Model Based System Design)という言葉を聞いて、どういう模型(model)を思い浮かべるだろうか。

計算機屋は、離散(digital)だろうし、
制御屋は、連続(analog)だろう。

WHAT IS MODEL-BASED SOFTWARE DEVELOPMENT?

MBSDが Model Based Software Developmentであったとしても、制御屋は離散モデルからコードの自動生成のことを意味している。

二つの模型の時間的、空間的な非連続性が、振る舞いの齟齬を産むらしい。
