The generalized kronecker product of two matrices.
# S4 method for class 'Expression,ANY'
kronecker(X, Y, FUN = "*", make.dimnames = FALSE, ...)
# S4 method for class 'ANY,Expression'
kronecker(X, Y, FUN = "*", make.dimnames = FALSE, ...)An Expression or matrix.
An Expression or matrix.
Hardwired to "*" for the kronecker product.
(Unimplemented) Dimension names are not supported in Expression objects.
(Unimplemented) Optional arguments.
An Expression that represents the kronecker product.
