Quadratic functions are essential in the world of mathematics and have a wide range of applications in various fields, such as physics, engineering, and finance. An inverse function can be thought of ...

It would be great to consider having a builtin inverse() function for matrices in WGLS. As pointed out in this comment, it is supported by other APIs. While it has been argued that this function is ...

In this paper we study the relations of four possible generalized inverses of a general distribution functions and their right-continuity properties. We correct a right-continuity result of the ...
