OperatingSystem is an option for file and related operations that specifies the type of operating system to use to determine file name and other conventions.

Building large software systems in Mathematica should follow the general principles that apply to building any large software system. The details may be unique to Mathematica ...

SystemsModelFeedbackConnect[sys] gives the closed-loop system for the StateSpaceModel or TransferFunctionModel object sys with unity negative feedback. ...

Version 8.0 introduces new features to load functions from shared libraries, giving a new way to incorporate external code into Mathematica. It also adds support for GPU ...

Names["string"] gives a list of the names of symbols which match the string. Names[patt] gives a list of names matching the arbitrary string pattern patt.

LinearSolveFunction[dimensions, data] represents a function for providing solutions to a matrix equation.

DiscreteTimeModelQ[expr] gives True if expr is a discrete-time StateSpaceModel or TransferFunctionModel object and False otherwise.

The unified architecture of Mathematica is highly extensible, allowing you to connect to other systems and programs. Using the MathLink communication protocol, which operates ...

EstimatorGains[ss, {p_1, p_2, ..., p_n}] gives the estimator gain matrix for the StateSpaceModel object ss, such that the poles of the estimator are p_i.

D[f, x] gives the partial derivative \[PartialD]f/\[PartialD]x. D[f, {x, n}] gives the multiple derivative \[PartialD]^n f/\[PartialD]x^n. D[f, x, y, ...] differentiates f ...
