The QuaternionAnalysis package is a collection of functions that adds functionalities to the Quaternions package for implementing Hamilton’s quaternion algebra. It also ...

The classical problem of a beam on a tensionless Winkler elastic foundation is reconsidered for the derivation of the conditions of complete contact between the beam and the ...

This textbook, the first of its kind, presents the fundamentals of distance geometry: theory, useful methodologies for obtaining solutions, and real world applications. ...

Given an N x N matrix, g a metric with lower indices; and x-, and N-vector (coordinates); EinsteinTensor[g,x] computes the Einstein tensor (an N x N matrix) with lower ...

This package includes functions for stability analysis of square numerical matrices and polynomials with numerical coefficients. Specifically, the number of roots z ...

This package provides some useful and efficient functions for treating polynomial matrices (i.e. matrices whose entries are univariate polynomials with rational or symbolic ...

The SIAM 100-Digit Challenge was a contest posed by Nick Trefethen of Oxford University in the January/February 2002 issue of SIAM News. This book shows in detail how each of ...

The classical complex-variable method of Muskhelishvili for the solution of general plane elasticity problems is revisited. The boundary conditions are satisfied ...

The solution to a system of n linear equations in n unknowns with integer coefficients is generally rational and not necessarily integer. For this reason, it would not appear ...

Many problems in plasma physics involve substantial amounts of analytical vector calculation. The complexity usually originates from both the vector operations themselves and ...
