Multiplies two distributed matrices, if they are conformable.
# S4 method for ddmatrix,ddmatrix
%*%(x, y)# S4 method for ddmatrix
crossprod(x, y = NULL)
# S4 method for ddmatrix
tcrossprod(x, y = NULL)
numeric distributed matrices
Returns a distributed matrix.
x and y must be conformable, on the same BLACS context, but
they need not be blocked with the same blocking dimension. The return will
default to the blocking dimension of x.
If you need to use x and y with differing blocking dimensions
and you want the return to have blocking different from that of x,
then use the function base.rpdgemm().
The crossprod() and tcrossprod() functions behave exactly as
their R counterparts.
