strncmpr 1.0

Compare last N chars of strings or cell stringsInput and output equal Matlab's STRNCMP/STRNCMPI, but the strings are compared from right to left.T = strncmpr(S1, S2, N) or T = strncmpir(S1, S2, N)INPUT: S1, S2: Strings or cell strings. N: Number of characters to compare.OUTPUT: T: Logical array, TRUE if the last N characters are equal, FALSE otherwise. For STRNCMPIR the case is ignored.Comparing just two strings in the backward direction can be done in Matlab with a fair efficiency. But for cell strings, this C-Mex is much faster than equivalent Matlab methods: e.g. 3% processing time for comparing a string with a {1 x 100} cell, 1% for {1 x 1000}. I apply it to identify the extensions of file names stored in cell strings.Call the unit-test function Teststrncmpr to check validity and speed.Tested: Matlab 6.5, 7.7, 7.8, WinXP, compatibility to Linux and OS-X assumed.Compiler: LCC2.4/3.8, BCC5.5, OpenWatcom 1.8, MSVC 2008.It is assumed that wchar_t has the same size as mxChar.Pre-compiled Mex: http://www.n-simon.de/mexI'd appreciate suggestions for improvements and bug reports sent through email - thanks
