Mathematica provides functions that allow users to write their own file format converters and integrate them with the Mathematica Import and Export framework. You can ...

Prime[n] gives the n\[Null]^th prime number.

StirlingS2[n, m] gives the Stirling number of the second kind \[ScriptCapitalS]_n^(m).

There are a number of important interactions in Mathematica between evaluation and pattern matching. The first observation is that pattern matching is usually done on ...

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 ...

The built-in function Reduce provides the functionality previously found in Algebra`InequalitySolve`.

RootSum[f, form] represents the sum of form[x] for all x that satisfy the polynomial equation f[x] == 0.

You can define wavelets to plug into the wavelet analysis framework by using the correct template. A wavelet wave is of the form wfam[args], where wfam is the symbol that ...

Wavelets are short wavelike functions that can be scaled and translated. Wavelet transforms take any signal and express it in terms of scaled and translated wavelets. The ...

HermitianMatrixQ[m] tests whether m is a Hermitian matrix.
