What does R(year)-a/b stands for in the version name?

In the version/release name, of the form R(year)-a/b, please describe the version name components completely.

R means "Release". Then there is the year, for example 2014. Then there is a letter a or b describing the release order in that year. "a" = first, "b" = second, etc. So R2014b means "Released in 2014" and the "b" means it is the second release that year, which typically happens in September. The "a" releases happen in March of each year.

Answer 2

Hello all, Is there is any difference related with internal features in between Matlab 2015 a and b

[Steven Lord]

See the Release Notes for information about the major changes and new features in each release. If you're specifically interested in release R2015b, the broadest impact change in that release is the new execution engine (see the Performance section of the Release Notes to which I linked.)

Answer 3

i thnik 'a' stands for academic and b stands for business

[Image Analyst]

No, "a" is the first release of the year (in March) , and "b" is the second release of the year (in September) as I said in my Answer. I'm certain of that.

[Steven Lord]

Image Analyst is correct. This page on the MathWorks website has a section talking about the release naming system as well as some motivation why we release twice yearly.
