SystemsModelDimensions[sys] gives the number of inputs and outputs of a StateSpaceModel or TransferFunctionModel object sys.

Magnify[expr, r] represents an object to be displayed with magnification r. Magnify[expr] displays with expr magnified by a fixed factor.

Sparse representations of matrices are useful because they do not store every element. If one particular value appears very frequently it can be very advantageous to use a ...

Mathematica notebooks include all the usual features of a top-quality word-processing system, plus many additional special capabilities. In all, there are over a thousand ...

Typical stylesheets make Mathematica automatically organize notebook cells into convenient groups. You can override this behavior, or control it in any way, using menu items, ...

Attributes for controlling numerical evaluation. Usually N goes inside functions and gets applied to each of their arguments. This tells Mathematica not to apply N to the ...

Mathematica has sophisticated built-in automatic numerical precision and accuracy control. But for special-purpose optimization of numerical computations, or for studying ...

The general principle that Mathematica follows in evaluating expressions is to go on applying transformation rules until the expressions no longer change. This means, for ...

In doing numerical operations like NDSolve and NMinimize, Mathematica by default uses machine numbers. But by setting the option WorkingPrecision->n you can tell it to use ...

Mathematica not only allows you to create interfaces within its usual notebook framework, but also to create complex standalone interfaces that customize the whole user ...
