x̂=(ATA)-1ATbx hat equals open paren cap A to the cap T-th power cap A close paren to the negative 1 power cap A to the cap T-th power b Orthonormal Matrices and Gram-Schmidt If a matrix has orthogonal columns of length 1, we call it . Orthonormal matrices are ideal because The takes independent columns and converts them into orthonormal columns . This yields another crucial matrix factorization: A=QRcap A equals cap Q cap R contains the orthonormal vectors and lecture notes for linear algebra gilbert strang

. While diagonalization only works for square matrices, SVD works for matrix. It breaks a transformation into a rotation ( cap V to the cap T-th power ), a stretching ( ), and another rotation (

His famous opening line in the 18.06 lectures is: “The fundamental problem of linear algebra is to solve a system of linear equations.” But he doesn't stop there. He immediately introduces the —the idea that solving ( Ax = b ) is about finding the right combination of the columns of ( A ).

decomposition was the first "factorization," the DNA of the matrix. The Big Picture: The Four Fundamental Subspaces

If row exchanges are required to avoid zero pivots, a permutation matrix is introduced, resulting in 3. The Four Fundamental Subspaces
