How do I align things in the following tabular environment? The column space of a matrix AAA is, as we already mentioned, the span of the column vectors v1\vec{v}_1v1, v2\vec{v}_2v2, v3\vec{v}_3v3, , vn\vec{v}_nvn (where nnn is the number of columns in AAA), i.e., it is the space of all linear combinations of v1\vec{v}_1v1, v2\vec{v}_2v2, v3\vec{v}_3v3, , vn\vec{v}_nvn, which is the set of all vectors www of the form: Where 1\alpha_11, 2\alpha_22, 3\alpha_33, n\alpha_nn are any numbers. Orthogonal Those big-headed scientists why did they invent so many numbers? calculate basis for the orthogonal column space To find the basis for the column space of a matrix, we use so-called Gaussian elimination (or rather its improvement: the Gauss-Jordan elimination ). Linear Algebra Calculators and the columns of Q contain an orthogonal basis for the column space of A. Math is the study of numbers, shapes, and patterns. I think you skipped the normalization part of the algorithm because you only want an orthogonal basis, and not an orthonormal basis. Visit our reduced row echelon form calculator to learn more! Orthogonal Projection Since 3+(3)1=03 + (-3)\cdot1 = 03+(3)1=0 and 2+21=0-2 + 2\cdot1 = 02+21=0, we add a multiple of (3)(-3)(3) and of 222 of the first row to the second and the third, respectively. In our case, this means that we divide the top row by 111 (which doesn't change a thing) and the middle one by 5-55: Our end matrix has leading ones in the first and the second column.
