Mathematica's notebook interface is a very powerful typesetting system that allows you to enter formulas as they are written in mathematical literature, using two-dimensional ...
TransferFunctionPoles[tf] gives a matrix of roots of the denominators in the TransferFunctionModel object tf.
EllipticPi[n, m] gives the complete elliptic integral of the third kind \[CapitalPi] (n \[VerticalSeparator] m). EllipticPi[n, \[Phi], m] gives the incomplete elliptic ...
Im
(Built-in Mathematica Symbol) Im[z] gives the imaginary part of the complex number z.
Re
(Built-in Mathematica Symbol) Re[z] gives the real part of the complex number z.
Special forms for some common symbols. This is equivalent to Sin[60Degree]. Here is the long form of the input.
Mathematically, sufficient conditions for a local minimum of a smooth function are quite straightforward: x^* is a local minimum if ∇f(x^*)=0 and the Hessian ∇^2f(x^*) is ...
Evaluating integrals is much more difficult than evaluating derivatives. For derivatives, there is a systematic procedure based on the chain rule that effectively allows any ...
GUIResolve[src] resolves an interface definition to its top-level completely loaded widget and enclosing widgets.GUIResolve[src, args] passes arguments to the interface ...
Even though the GUIKit widget expression was designed with user interface issues in mind, you can construct object trees unrelated to user interface widgets and still take ...
