Projection methods in linear algebra numerics
Linear algebra classes often jump straight to the definition of a projector (as a matrix) when talking about orthogonal projections in linear spaces. As often as it happens, it is…
Diagonalizing a matrix NOT having full rank: what does it mean?
This is going to be a quick intuition about what it means to diagonalize a matrix that does not have full rank (i.e. has null determinant). Every matrix can be…
Quick method to find line of shortest distance for skew lines
In linear algebra it is sometimes needed to find the equation of the line of shortest distance for two skew lines. What follows is a very quick method of finding…
