We need to apply the Gram-Schmidt Procedure anyway, and thus in this case the easiest thing to do is to start the Gram-Schmidt Procedure and throw out any vectors that would lead to division by 0(indicating linear indepen-dence), or stop when we reach a list of length four. To get started, we have e 1 = (1;2;3; 4) k(1;2;3; 4)k = 1 p 30; r 2 15 ...The Gram-Schmidt process treats the variables in a given order, according to the columns in X. We start with a new matrix Z consisting of X [,1]. Then, find a new variable Z [,2] orthogonal to Z [,1] by subtracting the projection of X [,2] on Z [,1]. Continue in the same way, subtracting the projections of X [,3] on the previous columns, and so ...We note that the orthonormal basis obtained by the Gram-Schmidt process from x 1;x 2;:::;x ‘ may be quite di erent from that obtained from generallized Gram-Schmidt process (a rearrangement of x 1;x 2;:::;x ‘). P.

Transform the basis x → 1 = [ 2 1] and x → 2 = [ 1 1] in R 2 to an orthonormal basis (i.e., perpendicular unit basis) using the Gram-Schmidt algorithm. Alright, so we need to find vectors R n and R n that are orthogonal to each other. First, we will let v → 1 equal x → 1, so.For example, the formula for a vector space projection is much simpler with an orthonormal basis.
