Arguments

lh_exp

An Expression or numeric constant representing the left-hand matrix.

rh_exp

An Expression or numeric constant representing the right-hand matrix.

object

A Kron object.

values

A list of arguments to the atom.

idx

An index into the atom.

arg_objs

A list of linear expressions for each argument.

dim

A vector with two elements representing the size of the resulting expression.

data

A list of additional data required by the atom.

Methods (by generic)

  • to_numeric(Kron): The kronecker product of the two values.

  • validate_args(Kron): Check both arguments are vectors and the first is a constant.

  • dim_from_args(Kron): The dimensions of the atom.

  • sign_from_args(Kron): The sign of the atom.

  • is_incr(Kron): Is the left-hand expression positive?

  • is_decr(Kron): Is the right-hand expression negative?

  • graph_implementation(Kron): The graph implementation of the atom.

Slots

lh_exp

An Expression or numeric constant representing the left-hand matrix.

rh_exp

An Expression or numeric constant representing the right-hand matrix.
