'代表转置,*代表乘法.
r=0:0.05:1表示r是一个行向量;
r'*cos(t)表示r转置后(为列向量)再乘以cos(t)!

Differences between Chinese and Western clothing

Clothing has always been a necessity as well as food and beverages, because you will see the ever-changing attire instead of a person who never wears clothes. On the other hand, as a social and cultural patterns, clothes not only reveals a nation's material and spiritual civilization, but also reflects the people's mental and emotional activities, being permeates in our daily life。

As a fact, Chinese and Western clothing cultures have formed their own clothing system in their own social environment. By now, life style is becoming more and more similar due to the development of economy and technology, as well as the global integration of commercial trade. Fashion is also following this trend. Western people are deeply impressed by rising China. This influence is easy to be found in Chinese clothing culture combined in Western designs. This brings us a series of thought: What are differences between Chinese and Western clothing cultures? Is there anything same between the two cultures? Should Chinese clothing refer more Western clothing culture or more Chinese clothing culture?

As the saying goes:"people rely on apparel, beauty relies on good make-up"。 I think this is the same between China and the West, but for the specific performance - it will be different.
