Mathematica's unified symbolic graphics architecture makes possible powerful mixing of programmatic graphics generation with interactive editing and control. The Mathematica ...

Arrowheads[spec] is a graphics directive specifying that arrows that follow should have arrowheads with sizes, positions, and forms specified by spec.

Functions to pick out pieces of polynomials. Here is an algebraic expression. This gives the coefficient of x in e.

A foundational idea in Mathematica is that all expressions—whatever they may represent—ultimately have a uniform tree-like structure.

ContinuousWaveletData[{{oct_1, voc_1} -> coef_1, ...}, wave] yields a continuous wavelet data object with wavelet coefficients coef_i corresponding to octave and voice ...
