Several of the linear algebra routines listed above are able to compute results for several matrices at once, if they are stacked into the same array. In linear algebra, a linear transformation that remains unchanged if applied twice (p(u) = p(p(u))), in other words, an idempotent operator. For example, the mapping that takes a point ( x , y , z ) in three dimensions to the point ( x , y , 0) in the plane is a projection. Linear algebra emerged in the 1800s yet spreadsheets were invented in the 1980s. I blame the gap on poor linear algebra education.

But from my linear algebra class, I remember hearing that OLS is indeed projection method. So I am confused here. What exactly is the difference between these two?

So the projection of x onto the column space is simply x. In fact, this makes since because when A is invertible, the system Ax=b has a unique solution for every b in Rn.

If it helps, I'm learning linear algebra for machine learning. I’m learning about vector projection right now, about learning more about one vector by its projection onto another vector. In linear algebra and functional analysis, a projection is a linear transformation P from a vector space to itself such that P 2 = P. That is, whenever P is applied twice to any value, it gives the same result as if it were applied once (idempotent). It leaves its image unchanged.

Inom matematikområdena linjär algebra och funktionalanalys är en projektion en linjär avbildning från ett vektorrum till sig själv sådant att = (man säger att är idempotent). En ortogonalprojektion är inom linjär algebra en metod att bestämma en uppdelning av en vektor v {\displaystyle v} i en del som ligger i ett underrum och den del som är ortogonal mot underrummet.
