4) The basic of tensor algebra (1) - Vector revisited

Tensor is, simply speaking, the expansion of vector. More strictly speaking, The tensor inherits the property of the vector, because the tensor is the superordinate concept of the vector. Once we took the subject of this article as ‘vector revisited’, let us start from the notion of the vector space. Wait, What is the vector, then?

Vector is the...

1) The basic of linear algebra (1) - what is the linear algebra?

There is the historical fact that in china, the equivalent procedure for the gauss elimination is used as early as 200 BC. The main use of the linear algebra is to solve the simultaneous equation system. In Nine Chapters of the Mathematical Art (九章算術), whose early version of this book was burnt by the...
