LerchPhi[z, s, a] gives the Lerch transcendent \[CapitalPhi] (z, s, a).

In data analysis, it is often necessary to clean a dataset before analyzing it. Data points with missing entries or that contain invalid values must be removed or replaced by ...

SetSharedFunction[f_1, f_2, ...] declares the symbols f_i as shared functions whose downvalues are synchronized among all parallel kernels.

The core of Mathematica's unique power for building interfaces is in its extremely flexible high-level symbolic paradigm. But Mathematica also allows you to build interfaces ...

MatrixPower[m, n] gives the n\[Null]\[Null]^th matrix power of the matrix m. MatrixPower[m, n, v] gives the n\[Null]^th matrix power of the matrix m applied to the vector v.

Count[list, pattern] gives the number of elements in list that match pattern. Count[expr, pattern, levelspec] gives the total number of subexpressions matching pattern that ...

Structural operations on polynomials. Here is a polynomial in one variable. Expand expands out products and powers, writing the polynomial as a simple sum of terms.

Directly integrated into the Mathematica language is a convenient symbolic options mechanism that allows arbitrary sequences of named parameters to be given to both built-in ...

expr //. rules repeatedly performs replacements until expr no longer changes.

Chop[expr] replaces approximate real numbers in expr that are close to zero by the exact integer 0.
