Gram schmidt example.

For classical Gram-Schmidt, the second to last line would be. y3=y3- (q2'*x3)*q2; instead, but that would be the only difference (in the 3x3 setting). The stability issue is that you do arithmetic with y3, introducing some rounding errors in those digits, and then you multiply them by roughly 1012 10 12 when you normalize to make q3.

Of 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).Example Euclidean space Consider the following set of vectors in R2 (with the conventional inner product ) Now, perform Gram–Schmidt, to obtain an orthogonal set of vectors: We check that the vectors u1 and u2 are indeed orthogonal: noting that if the dot product of two vectors is 0 then they are orthogonal.Vectors and spaces VectorsPROBLEM SETS.
