Gram–Schmidt process - Wikipedia

WebOf course, nobody wants to do things like the Gram Schmidt algorithm by hand. Fortunately, there's a function for that. If we have vectors X,Y,Z, we can make a list L=[X,Y,Z], and perform Gram Schmidt with GramSchmidt(L). If you want your output to be an orthonormal basis (and not merely orthogonal), then you can use GramSchmidt(L,true).

When this process is implemented on a computer, the vectors are often not quite orthogonal, due to rounding errors. For the Gram–Schmidt process as described above (sometimes referred to as "classical Gram–Schmidt") this loss of orthogonality is particularly bad; therefore, it is said that the (classical) Gram–Schmidt process is numerically unstable. The Gram–Schmidt process can be stabilized by a small modification; this version is sometime… Web4 hours ago · Using the QR algorithm, I am trying to get A**B for N*N size matrix with scalar B.
