GridDefaultElement is an option for the low-level function GridBox that specifies what to insert when a new element is created interactively in a GridBox.
FreeQ
(Built-in Mathematica Symbol) FreeQ[expr, form] yields True if no subexpression in expr matches form, and yields False otherwise. FreeQ[expr, form, levelspec] tests only those parts of expr on levels ...
Intersection[list_1, list_2, ...] gives a sorted list of the elements common to all the list_i.
SpheroidalPSPrime[n, m, \[Gamma], z] gives the derivative with respect to z of the angular spheroidal function PS n, m (\[Gamma], z) of the first kind.
SpheroidalQSPrime[n, m, \[Gamma], z] gives the derivative with respect to z of the angular spheroidal function QS n, m (\[Gamma], z) of the second kind.
Apply
(Built-in Mathematica Symbol) Apply[f, expr] or f @@ expr replaces the head of expr by f. Apply[f, expr, {1}] or f @@@ expr replaces heads at level 1 of expr by f.Apply[f, expr, levelspec] replaces heads ...
Formatting lists as tables and matrices. Here is a list. Grid gives the list typeset in a tabular format.
MatrixPlot[m] generates a plot that gives a visual representation of the values of elements in a matrix.
DateFunction is an option for DateListPlot that specifies how dates given as input should be converted to date lists.
SingularValueList[m] gives a list of the nonzero singular values of a matrix m. SingularValueList[{m, a}] gives the generalized singular values of m with respect to a. ...
