Parallel projection

This article uses too much jargon, which needs explaining or simplifying. Please help improve the page to make it understandable for everybody, without removing the technical details. (February 2024)

In linear algebra and functional analysis, a projection is a linear transformation P from a vector space to itself such that P² = P. Projections map the whole vector space to a subspace and leave the points in that subspace unchanged.
