Remove[symbol_1, ...] removes symbols completely, so that their names are no longer recognized by Mathematica. Remove["form_1", "form_2", ...] removes all symbols whose names ...

ToNumberField[a, \[Theta]] expresses the algebraic number a in the number field generated by \[Theta]. ToNumberField[{a_1, a_2, ...}, \[Theta]] expresses the a_i in the field ...

GraphLayout is an option to Graph and related functions that specifies what layout to use for graph components and collections of components.

JordanModelDecomposition[ss] yields the Jordan decomposition of a StateSpaceModel object ss. The result is a list {s, jc} where s is a similarity matrix and jc is the Jordan ...

Special forms for some common symbols. This is equivalent to Sin[60Degree]. Here is the long form of the input.

Output formats for numbers. These numbers are given in the default output format. Large numbers are given in scientific notation. This gives all numbers in scientific ...

ArrayFlatten[{{m_11, m_12, ...}, {m_21, m_22, ...}, ...}] creates a single flattened matrix from a matrix of matrices m i j. ArrayFlatten[a, r] flattens out r pairs of levels ...

lhs := rhs assigns rhs to be the delayed value of lhs. rhs is maintained in an unevaluated form. When lhs appears, it is replaced by rhs, evaluated afresh each time.

Mathematica's symbolic architecture allows a unique representation and treatment of images in both programs and documents. Mathematica supports images with arbitrary numbers ...

Developed at Wolfram Research over nearly twenty years, Mathematica has by far the world's most sophisticated and convenient mathematical typesetting technology. Generalizing ...
