### activity | operation | matrix operation:

Matrix inversion
* are matrix operations.
* is simply the special case where is an unit matrix
  - used extensively in computer graphics
+ Invertible matrix: Linear algebra
  * There are algorithms to calculate the inverse of a matrix, for example Gaussian elimination. The problem is that finding the inverse is relatively 'expensive' to do for big matrices. Matrix inversion is used extensively in computer graphics.
