This video is No Exception, describing the concepts of inverse matrices, column space, rank and, uh no, space through that lens.
这个视频是《无一例外》，描述了逆矩阵，列空间，秩，还有，不，通过这个镜头的空间。
Linear algebra
It's that you come away with a strong intuition for inverse matrices, column space and no space, and that those intuitions make any future learning that you do more fruitful.
你会对逆矩阵 列空间和无空间有很强的直觉 这些直觉会让你以后的学习更有成效。

Invertible matrix
In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate) if there exists an n-by-n square matrix B such that
where In denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case, then the matrix B is uniquely determined by A and is called the inverse of A, denoted by A.
