an inversion formula, which shows that every symmetric, banded matrix corresponds uniquely to a Sturm–Liouville eigenvalue problem of the above form; 2. a formula for the characteristic polynomial of A, which yields a recursion for its calculation; 3. an oscillation theorem, which generalizes ...
Finding the Sum and Difference of Two MatricesTo solve a problem like the one described for the soccer teams, we can use a matrix, which is a rectangular array of numbers. A row in a matrix is a set of numbers that are aligned horizontally. A column in a matrix is a set of ...
Difference equations, spline approximations and multiperiod linear programs all give rise to linear equation systems that have a characteristic staircase structure. A staircase system's variables can be partitioned, into a natural sequence of periods, in such a way that every equation involves at most...

We prove that the existence of a cocyclic Hadamard matrix of order 4t is equivalent to the existence of a normal relative difference set with parameters (4t,2,4t,2t). In the basic case we note there is a corresponding equivalence between coboundary Hadamard matrices and Menon–Hadamard ...

Bode's concepts of return difference and return ratio are shown to play a fundamental role in the analysis of multivariable feedback control systems. Matrix transfer functions are regarded as operators on linear vector spaces over the field of rational functions in the complex variable s. The eige...
摘要: In this paper, we introduce some kinds of matrices in combinatorial design, and give the relationship between the matrix and combinatorial theory. Then we find the matrix is very important, when it is used in design field, it will make the describing very clear and concise.关键词:...
