Install
(Built-in Mathematica Symbol) Install["name"] starts a MathLink-compatible external program and installs Mathematica definitions to call functions in it.
InverseFourierCosTransform[expr, \[Omega], t] gives the symbolic inverse Fourier cosine transform of expr. InverseFourierCosTransform[expr, {\[Omega]_1, \[Omega]_2, \ ...}, ...
InverseFourierSinTransform[expr, \[Omega], t] gives the symbolic inverse Fourier sine transform of expr. InverseFourierSinTransform[expr, {\[Omega]_1, \[Omega]_2, \ ...}, ...
ListLinePlot[{y_1, y_2, ...}] plots a line through a list of values, assumed to correspond to x coordinates 1, 2, .... ListLinePlot[{{x_1, y_1}, {x_2, y_2}, ...}] plots a ...
TagSet
(Built-in Mathematica Symbol) f /: lhs = rhs assigns rhs to be the value of lhs, and associates the assignment with the symbol f.
Throw
(Built-in Mathematica Symbol) Throw[value] stops evaluation and returns value as the value of the nearest enclosing Catch. Throw[value, tag] is caught only by Catch[expr, form] where form is a pattern ...
Mathematica 8 provides functions that allow developers to implement file format converters to be integrated with the Mathematica Import and Export framework. You can ...
Sometimes you may want to set up functions where certain arguments, if omitted, are given "default values". The pattern x_:v stands for an object that can be omitted, and if ...
Mathematica allows you to use special notation for many common operators. For example, although internally Mathematica represents a sum of two terms as Plus[x,y], you can ...
Invisible characters. In the input there is an invisible comma between the 1 and 2. Here there is an invisible space between the x and y, interpreted as multiplication.
