Example of gram schmidt process.

The Gram-Schmidt Process. The Gram-Schmidt process takes a set of k linearly independent vectors, vi, 1 ≤ i ≤ k, and builds an orthonormal basis that spans the same subspace. Compute the projection of vector v onto vector u using. The vector v −proj u ( v) is orthogonal to u, and this forms the basis for the Gram-Schmidt process.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 ...Returns ----- G : ndarray, Matrix of orthogonal vectors Gram-Schmidt Process ----- The Gram–Schmidt process is a simple algorithm for producing an orthogonal or orthonormal basis for any nonzero subspace of Rn. The process is independent of what bilinear form you are using.
