Thank you all for you time and your help.

It's to let you interleave calls. You can call MatAssemblyBegin as soon as
you've finished assembling the matrix, but you need not call MatAssemblyEnd
until you require more operations on A.
So you can build A (call Begin), build B (call Begin), build a vector x and b,
and only call
