rank of a matrix
41Growth-share matrix — The BCG matrix (aka B.C.G. analysis, BCG matrix, Boston Box, Boston Matrix, Boston Consulting Group analysis) is a chart that had been created by Bruce Henderson for the Boston Consulting Group in 1970 to help corporations with analyzing their… …
42Block matrix pseudoinverse — is a formula of pseudoinverse of a partitioned matrix. This is useful for decomposing or approximating many algorithms updating parameters in signal processing, which are based on least squares method. Derivation Consider a column wise… …
43Polynomial matrix — Not to be confused with matrix polynomial. A polynomial matrix or sometimes matrix polynomial is a matrix whose elements are univariate or multivariate polynomials. A λ matrix is a matrix whose elements are polynomials in λ. A univariate… …
44Shear matrix — In mathematics, a shear matrix is an elementary matrix that represents the addition of a multiple of one row or column to another. Such a matrix may be derived by taking the identity matrix and replacing one of the zero elements with a non zero… …
45Rang einer Matrix — Der Rang ist innerhalb der Mathematik ein Begriff aus dem Teilgebiet der linearen Algebra. Man ordnet ihn einer linearen Abbildung oder einer Matrix zu. Übliche Schreibweisen sind rang(f) und rg(f). Selten werden auch die englischen Schreibweisen …
46Centering matrix — In mathematics and multivariate statistics, the centering matrix [John I. Marden, Analyzing and Modeling Rank Data , Chapman Hall, 1995, ISBN 0412995212, page 59.] is a symmetric and idempotent matrix, which when multiplied with a vector has the… …
47Bézout matrix — In mathematics, a Bézout matrix (or Bézoutian) is a special square matrix associated to two polynomials. Such matrices are sometimes used to test the stability of a given polynomial.DefinitionLet f ( z ) and g ( z ) be two complex polynomials of… …
48Finite rank operator — In functional analysis, a finite rank operator is a bounded linear operator between Banach spaces whose range is finite dimensional. Finite rank operators on a Hilbert space A canonical form Finite rank operators are matrices (of finite size)… …
49Decision matrix — A decision matrix is a list of values in rows and columns that allows an ologist to systematically identify, analyze, and rate the performance of relationships between sets of values and information. Elements of a decision matrix show decisions… …
50Dartboard optimization matrix — or DOM methodology is the way of optimizing a website for search engines using white hat techniques. DOM involves mapping your website pages and keywords in concentric rings, similar to a dart board. The aim of the process is to come up with a… …
