Weights
(Built-in Mathematica Symbol) Weights is an option for various fitting and other functions which specifies weights to associate with data elements.
WheelGraph[n] gives the wheel graph with n vertices W_n.
Which
(Built-in Mathematica Symbol) Which[test_1, value_1, test_2, value_2, ...] evaluates each of the test_i in turn, returning the value of the value_i corresponding to the first one that yields True.
While
(Built-in Mathematica Symbol) While[test, body] evaluates test, then body, repetitively, until test first fails to give True.
White
(Built-in Mathematica Symbol) White represents the color white in graphics or style specifications.
WhitespaceCharacter represents a single whitespace character in StringExpression.
Whitespace represents a sequence of whitespace characters in StringExpression.
WhittakerM[k, m, z] gives the Whittaker function M k, m (z).
WhittakerW[k, m, z] gives the Whittaker function W k, m (z).
WienerFilter[image, r] removes noise from image by applying a range-r Wiener filter.WienerFilter[image, r, ns] assumes an additive noise power value ns.
