[VALUE,INDEX] = FINDFIRST(A,SEARCHDIR)
Returns the value and optionally index of the first non-zero in A.
A must be full and double
If SEARCHDIR = 'first' (default) the search is from the first index
If SEARCHDIR = 'last', the search is backwards from the last index

This is a cmex file, and is an order of magnitude faster than using FIND, and two orders of magnitude faster than using MATLAB loops.

Tested on Windows NT/2000 VC 6.0, Linux (gcc 2.95) and Solaris (courtesy A Pearson)
