[petsc-users] On the usage of MatSetValuesBlocked

[Edoardo alinovi]

Barry,

Thanks, yes, I should pass 1 and not 3.... For some reason I have
misunderstood the wording in the documentation and I have interpreted m and
n as the number of row and columns of the block to insert, while I need to
think of everything as divided by bs... Now I am with you!!!

Many thanks and sorry to have been so dump! 😓
