matlab学习的基础例题，哪本书的记不太清楚了，不过可以准确说这是适合自动化本科生初学matlab的例题。(the based list)

In linguistic morphology, stemming is the process for reducing inflected (or sometimes derived) words to their stem, base or root form – generally a written word form. The stem need not be identical to the morphological root of the word it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. The algorithm has been a long-standing problem in computer science.
