Linear algebra projection

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. In such a case, the simplification A (A^T A) ^ (-1) A^T =A A^ (-1) A^T^ (-1) A^T=I would be valid. So the projection of x onto the column space is simply x.

Which is equivalent to Sal's answer. Comment on bryan's post “v actually is not the unit vector. The unit vecto”. 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 ). Answer: There are two ways to determine projection vector p. Method 1: Determine the coefficient vector x ö based on A T e=0, then determine p from p=Ax ö .
