It is implemented in scripts/plot/util/subplot.m for all toolkits.

I am in the process of refactoring subplot.m so that it behaves more like
Matlab does. I haven't assigned the bug to my self, but if no body is
already working on this I'll do so. Also if someone who has already worked
on the current implementation has comments/advises, they are welcome (either
here or on the bug tracker).
