Returns numeric representation of Matlab version
>> version = matlab_version_num
The version number returned is not the true Matlab version, but one which
numerical places Matlab versions in chronological order
e.g. if R2011b i.e. version 7.13:
>> matlab_version_num
ans =
7.1300
e.g. if R2007a i.e. version 7.4:
>> matlab_version_num
ans =
7.0400 (i.e. not 7.4)
