C-Mex: anyEqThis is a simple but fast check, if two arrays contain any common element.If no common element is found, the C-Mex is 30% to 50% faster than the equivalent Matlab expression "any(X(:) == y)" and much faster than "any(ismember(X, Y))" if Y is an array.If a matching element is found early, this function returns very fast without testing the rest.In opposite to the Matlab version, the C-mex does not need any temporary arrays.R = anyEq(X, Y)INPUT: X, Y: Arrays, arbitrary size. The order of X and Y does not influence the speed. Types: DOUBLE, SINGLE, (U)INT8/16/32/64, CHAR.OUTPUT: R: TRUE if X and Y have any common element.Tested: Matlab 6.5, 2008a/b, 2009a, 2011b, 32/64 bitLCC, BCC, OWC, MSVC 2008 and 2010, WinXP and Win7.Assumed compatibility: Linux, MacOS.Pre-compiled Mex: http://www.n-simon.de/mexSuggestion and bugreports through the author page of the FEX or by email are appreciated.
