Vectors, Matrices and Coordinate Transformations
For our purposes we will think of a vector as a mathematical representation of a physical entity which has both magnitude and direction in a 3D space. Examples of physical vectors are forces, moments, and velocities. Geometrically, a vector can be represented as arrows. The length of the arrow represents its magnitude. Unless indicated otherwise, we shall assume that parallel translation does n...
متن کاملCompact Difference Bound Matrices
The Octagon domain, which tracks a restricted class of two variable inequality, is the abstract domain of choice for many applications because its domain operations are either quadratic or cubic in the number of program variables. Octagon constraints are classically represented using a Difference Bound Matrix (DBM), where the entries in the DBM store bounds c for inequalities of the form xi ́ x...
متن کاملOn Generalized Hadamard Matrices and Difference Matrices: Z6
(Caution: please note Jennifer Seberry has tried but been unable to contact the persons named as co-authors. Apolgogies for half finished results.) We note that the literature on this subject is very disorganized. Authors have not read the literature on their own key-words and papers thus ignored, on the other hand papers have been claimed to be published which have not. We have put together th...
متن کاملExploiting Sparsity in Difference-Bound Matrices
Relational numeric abstract domains are very important in program analysis. Common domains, such as Zones and Octagons, are usually conceptualised with weighted digraphs and implemented using difference-bound matrices (DBMs). Unfortunately, though conceptually simple, direct implementations of graph-based domains tend to perform poorly in practice, and are impractical for analyzing large code-b...
متن کاملNonlinear Difference Equations and Stokes Matrices
We study one scalar holomorphic function of finitely many complex variables which, under the assumption that one of the two coefficient matrices has all distinct eigenvalues, allows to calculate the Stokes multipliers of Okubo’s confluent hypergeometric system. Many properties of this function, including a nonlinear functional equation, are obtained. An open question is whether the function is ...
