HoldComplete[expr] shields expr completely from the standard Mathematica evaluation process, preventing even upvalues associated with expr from being used.
ImageAdjust[image] adjusts the levels in image, rescaling them to cover the range 0 to 1.ImageAdjust[image, c] adjusts the contrast of image by an amount c.ImageAdjust[image, ...
Intersection[list_1, list_2, ...] gives a sorted list of the elements common to all the list_i.
InverseFunctions is an option for Solve and related functions that specifies whether inverse functions should be used.
InverseGudermannian[z] gives the inverse Gudermannian function gd -1 (z).
MeanShiftFilter[image, r, d] replaces each pixel with the mean of the pixels in a range-r neighborhood and whose value is within a distance d.MeanShiftFilter[array, r, d] ...
MeanShift[list, d] replaces each element in list by the mean of the values of all elements that differ by less than d.
Not
(Built-in Mathematica Symbol) ! expr is the logical NOT function. It gives False if expr is True, and True if it is False.
Parallelization is an option for Compile that specifies whether it should create a compiled function that could run in parallel.
PermutationSupport[perm] returns the support of the permutation perm.
