Web$\begingroup$ Note that to use this we must have a basis already chosen (to write down matrices) and that our inner product must match the standard dot product in terms of this basis (so that matrix multiplication corresponds to taking inner product of rows of the left matrix with columns of the right matrix). Also, to apply the first comment, the number of … WebDescription. Q = orth (A) returns an orthonormal basis for the range of A. The columns of matrix Q are vectors that span the range of A. The number of columns in Q is equal to the rank of A. Q = orth (A,tol) also specifies a tolerance. Singular values of A less than tol are treated as zero, which can affect the number of columns in Q. black square cufflinks
