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.
