matmult | R Documentation |
Multiplies two distributed matrices, if they are conformable.
## S4 method for signature 'ddmatrix,ddmatrix'
x %*% y
## S4 method for signature 'ddmatrix'
crossprod(x, y = NULL)
## S4 method for signature 'ddmatrix'
tcrossprod(x, y = NULL)
x , y |
numeric distributed matrices |
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.
Returns a distributed matrix.
