I need to change the size of the block LU factorisation, can you help me?
As far as I can see, this functionality is not implemented yet, but it does seem a reasonable request. If you don't mind changing the source code, I guess the only thing you need to do is to change the default for the argument maxBlockSize in blocked_lu() in PartialPivLU.h from 256 to whatever you want.
