The post QR Decomposition with the Gram-Schmidt Algorithm appeared first on Aaron Schlegel.4.4 Modified Gram-Schmidt The classical Gram-Schmidt algorithm is based on projections of the form v j = a j − Xj−1 i=1 r ijq i = a j − Xj−1 i=1 (q∗ i a j)q i. Note that this means we are performing a sequence of vector projections. The starting point for the modified Gram-Schmidt algorithm is to rewrite one step of the classical1 Answer. There are different ways to calculate the QR decomposition of a matrix. The main methods are: Gram-Schmidt is a sequence of projections and vector subtractions, which may be implemented as a sequence of kernels performing reductions (for projections) and element-wise array operations (vector subtractions).

QR decomposition.

"Classical Gram-Schmidt, in which you subtract off the projections of the (k+1)th vector onto the first k vectors, is quite unstable, especially in high dimensions, because you essentially ensure that your new vector is orthogonal to the input vector in question but fail to ensure that the vectors you get at the end of the process are ...I know that we can use Gram-Schmidt to construct an orthonormal basis, but the natural basis for this space (where every ij-th element is $1$ and the rest $0$) is just that - every matrix there is orthogonal to the rest, and each norm equals $1$.It is rather difficult to show the Gram–Schmidt procedure for the specific vectors utilized in our example. This being the case, Fig. 3.18 shows a more stylized conceptualization of the procedure.
