Processing Textual Data (Mathematica Guide)

Mathematica has uniquely flexible capabilities for processing large volumes of textual data. Most often data represented as a string is converted to lists or other constructs ...

CoefficientRules (Built-in Mathematica Symbol)

CoefficientRules[poly, {x_1, x_2, ...}] gives the list {{e_11, e_12, ...} -> c_1, {e_21, ...} -> c_2, ...} of exponent vectors and coefficients for the monomials in poly with ...

Functional Iteration (Mathematica Guide)

Long used in its simplest form in mathematics, functional iteration is an elegant way to represent repeated operations. Mathematica's symbolic architecture makes powerful ...

Functional Programming (Mathematica Guide)

Long viewed as an important theoretical idea, functional programming finally became truly convenient and practical with the introduction of Mathematica's symbolic language. ...

Symbol Handling (Mathematica Guide)

Mathematica symbols are the ultimate atoms of symbolic data. Every symbol has a unique name, exists in a certain Mathematica context or namespace, and can have a variety of ...

Append (Built-in Mathematica Symbol)

Append[expr, elem] gives expr with elem appended.

Part (Built-in Mathematica Symbol)

expr[[i]] or Part[expr, i] gives the i\[Null]^th part of expr. expr[[-i]] counts from the end. expr[[i, j, ...]] or Part[expr, i, j, ...] is equivalent to expr[[i]][[j]] .... ...

Prepend (Built-in Mathematica Symbol)

Prepend[expr, elem] gives expr with elem prepended.

In (Built-in Mathematica Symbol)

In[n] is a global object that is assigned to have a delayed value of the n\[Null]^th input line.

Rules (Mathematica Guide)

Everything that Mathematica does can be thought of as derived from its ability to apply general transformation rules to arbitrary symbolic expressions. The Mathematica ...
