ViewCenter (Built-in Mathematica Symbol)

ViewCenter is an option for Graphics3D and related functions which gives the scaled coordinates of the point which should appear at the center of the final image.

Derived Statistical Distributions (Mathematica Guide)

Derived distributions are modifications to existing distributions. There is a variety of ways in which you can arrive at modified distributions, including functions of random ...

DiscreteConvolve (Built-in Mathematica Symbol)

DiscreteConvolve[f, g, n, m] gives the convolution with respect to n of the expressions f and g. DiscreteConvolve[f, g, {n_1, n_2, ...}, {m_1, m_2, ...}] gives the ...

Basic Matrix Operations (Mathematica Tutorial)

Some basic matrix operations. Transposing a matrix interchanges the rows and columns in the matrix. If you transpose an m×n matrix, you get an n×m matrix as the result. ...

EllipticK (Built-in Mathematica Symbol)

EllipticK[m] gives the complete elliptic integral of the first kind K(m).

MemberQ (Built-in Mathematica Symbol)

MemberQ[list, form] returns True if an element of list matches form, and False otherwise. MemberQ[list, form, levelspec] tests all parts of list specified by levelspec.
