As the world's best-developed tree-oriented symbolic language, Mathematica is uniquely suited to working with XML. Not only can Mathematica generate XML from scratch, it can ...

ControllableModelQ[ss] yields True if the StateSpaceModel object ss is controllable, and False otherwise.

ObservableModelQ[ss] gives True if the StateSpaceModel object ss is observable, and False otherwise.

Mathematica's approach to differential operators provides both an elegant and a convenient representation of mathematical structures, and an immediate framework for strong ...

LogPlot[f, {x, x_min, x_max}] generates a log plot of f as a function of x from x_min to x_max. LogPlot[{f_1, f_2, ...}, {x, x_min, x_max}] generates log plots of several ...

patt /; test is a pattern which matches only if the evaluation of test yields True. lhs :> rhs /; test represents a rule which applies only if the evaluation of test yields ...

Eigenvalues and eigenvectors. The eigenvalues of a matrix m are the values λ_i for which one can find nonzero vectors v_i such that m.v_i λ_iv_i. The eigenvectors are the ...
