I have adapted the pcg function to accept bloc right hand sides. A bit of cleaning is still needed (as for example reducing the number of unneeded calls to pinv). As well as a bit of testing.
As this has for effect to slightly increase CPU cost for simple right hand sides, I created an independant function, but if you prefer, it can easily be integrated into the default pcg.

Are you interested in such a function ?
