tsnnls: A solver for large sparse least squares
... the intermediate stages of the calculation, we only use xF and yG to search for infeasible variables to shift between F and G. So we need only calculate correct signs for all the variables— beyond this the numerical quality of these solutions is unimportant. But the last solution of Equations 4 and ...

The Householder transformation in numerical linear
... How long does it take to compute and apply all these Mi ’s, though? It can be shown (but I will not show in this paper) that the Gaussian-elimination and Householder methods for upper-triangularization are on the order of n3 . Thus, these methods are far more efficient than naive cofactor expansion. ...

... 1. While pivots are indeed always 1, anything except 0 can be turned into a 1 by row operations. Students were awarded partial credit for correct conclusions based on arithmetic errors, as long as those conclusions were not contradictory (for example, concluding that there are no solutions when z = ...

Generic Linear Algebra and Quotient Rings in Maple - CECM
... Echelon form works over any field that the user constructs. In contrast, Maple’s facilities for linear algebra in its LinearAlgebra package only work for specific rings. If the input matrix contains general expressions, the algorithms may work incorrectly. Motivated by a need to do linear algebra ov ...

... We will follow the "RC convention" for numbering elements of a matrix, where Aij is the element of matrix A in its i-th row and j-th column. As an example, in the matrix above, the elements which are equal to -1 are A13, A21, and A34. C. The transpose of a matrix. The transpose A T of a matrix A is ...

Non-negative matrix factorization
NMF redirects here. For the bridge convention, see new minor forcing.Non-negative matrix factorization (NMF), also non-negative matrix approximation is a group of algorithms in multivariate analysis and linear algebra where a matrix V is factorized into (usually) two matrices W and H, with the property that all three matrices have no negative elements. This non-negativity makes the resulting matrices easier to inspect. Also, in applications such as processing of audio spectrograms non-negativity is inherent to the data being considered. Since the problem is not exactly solvable in general, it is commonly approximated numerically.NMF finds applications in such fields as computer vision, document clustering, chemometrics, audio signal processing and recommender systems.
