WebIn linear algebra, a projection matrix is a matrix associated to a linear operator that maps vectors into their projections onto a subspace. Preliminary notions Let us start by reviewing some notions that are essential for understanding projections. Let be a linear space. Let and be subspaces of . Remember that the sum is the set In linear algebra and functional analysis, a projection is a linear transformation $${\displaystyle P}$$ from a vector space to itself (an endomorphism) such that $${\displaystyle P\circ P=P}$$. That is, whenever $${\displaystyle P}$$ is applied twice to any vector, it gives the same result as if it were applied … See more Idempotence By definition, a projection $${\displaystyle P}$$ is idempotent (i.e. $${\displaystyle P^{2}=P}$$).
