What is throwing me off is the fact that here I'm not looking for the projection of y onto a vector, I'm looking for the projection of y onto the span of two vectors. How do I deal with that? linear-algebra
It's easy to prove that the minimum is attained for the orthogonal projection, i.e. for x: (Ax − b) ⊥ col(A), or in matrix notation, At(Ax − b) = AtAx − Atb = 0 If the columns of A are linearly independent, the solution is x = (AtA) − 1Atb It is both (b) the least squares solution and (a) the coordinates of the orthogonal projection ...
The spanning set is orthonormal, so you simply add up the projections onto them: (v ⋅v1)v1 + (v ⋅v2)v2. (v ⋅ v 1) v 1 + (v ⋅ v 2) v 2. As saulspatz hinted, this is exactly what you do to find the coordinates of v v relative to the standard basis, i.e., v =xve1 +yve2 = (v ⋅e1)e1 + (v ⋅e2)e2 v = x v e 1 + y v e 2 = (v ⋅ e 1) e 1 ...
1 Answer. Sorted by: 6. You can easily check for A considering the product by the basis vector of the plane, since ∀v ∀ v in the plane must be: Av = v A v = v. Whereas for the normal vector: An = 0 A n = 0. Note that with respect to the basis B: c1,c2, n B: c 1, c 2, n the projection matrix is simply:

There is a general answer to this question that doesn't depend on the vectors being given as orthogonal. Consider the orthogonal projection onto the span of $\{ a_1,a_2,\dots,a
Choose a point p0 = (x0,y0)T on the given line. Move the origin to p0 (later move back). Then the line can be represented by a vector v, and the original given point becomes p1 = p −p0. Now compute vvT vTvp1. Then move the origin back, we get the orthogonal projection in the original coordinate system is.
Orthogonal projections are with respect to something; I suspect that you want the orthogonal projection onto the plane the two vectors generate. If so, then you need to state that. $\endgroup$ – Arturo Magidin
