Description

Multiplies two distributed matrices, if they are conformable.

Usage

## S4 method for signature 'shaq,matrix'
x %*% y

Arguments

x	A shaq.
y	A regular matrix, globally owned on all ranks. Since the number of columns of a shaq should be small, this matrix should be small as well.

Value

A shaq.

Communication

The operation is completely local.
