Compare Matlab version to specified number
In opposite to other similar functions in the FEX, this function is not confused by the version numbers 7.10 (2010a) and 7.1 (R14SP3). Also failing:
sscanf(version, '%f', 1) <= 7.8
and VERLESSTHAN published by Matlab:
This C-Mex function takes about 0.6% of the processing time needed by Matlab's VERLESSTHAN('matlab'), so it can be used in repeatedly called functions without wasting too much time.
Match = isMatlabVer(Relop, N)
Relop: Comparison operator as string: '<', '<=', '>', '>=', '=='.
N: Number to compare with as DOUBLE vector with 1 to 4 elements.
Match: TRUE if matching, FALSE otherwise.
version '184.108.40.2062 (R2009a)' (different results for other version!)
isMatlabVer('<=', 7) % TRUE
isMatlabVer('>', 6) % TRUE
isMatlabVer('<', [7, 8]) % FALSE
isMatlabVer('<=', [7, 8]) % TRUE
isMatlabVer('>', [7, 8, 0, 342]) % FALSE
isMatlabVer('==', 7) % TRUE
isMatlabVer('==', [7, 10]) % FALSE
isMatlabVer('>', [7, 8, 0]) % FALSE (the 342 is not considered!)
version '220.127.116.11 (2010a)':
isMatlabVer('>', [7, 2]) % TRUE

I'd appreciate suggestions for improvements and bug reports sent through email - thanks.
