Mathematica provides several convenient methods for extracting and manipulating parts of matrices. The flexible [[ ]] (Part) and ;; (Span) syntaxes provide compact yet ...

EndOfString represents the end of a string for purposes of matching in StringExpression.

StartOfString represents the start of a string for purposes of matching in StringExpression.

Mathematica provides systemwide support for a large number of special characters. Each character has a name and a number of shortcut aliases. They are fully supported by the ...

LinearSolveFunction[dimensions, data] represents a function for providing solutions to a matrix equation.

Mathematica's unified symbolic architecture allows immediate generalization of part-oriented list operations to arbitrary expressions —supporting operations both on ...

Mathematica provides a carefully chosen set of functions for accessing elements of lists either using indices or positions, or using patterns or criteria for their values.

ProductLog[z] gives the principal solution for w in z == w e^w. ProductLog[k, z] gives the k\[Null]^th solution.

Lists are very important structures in Mathematica. Lists allow you treat any kind of collection of objects as a single entity. Sometimes you need to pick out or extract ...

Many of the most powerful list manipulation operations in Mathematica treat whole lists as single objects. Sometimes, however, you need to pick out or set individual elements ...
