The Promote class.
This class represents the promotion of a scalar expression into a vector/matrix.
Promote(expr, promoted_dim) ## S4 method for signature 'Promote' to_numeric(object, values) ## S4 method for signature 'Promote' is_symmetric(object) ## S4 method for signature 'Promote' dim_from_args(object) ## S4 method for signature 'Promote' is_atom_log_log_convex(object) ## S4 method for signature 'Promote' is_atom_log_log_concave(object) ## S4 method for signature 'Promote' get_data(object) ## S4 method for signature 'Promote' graph_implementation(object, arg_objs, dim, data = NA_real_)
expr |
An Expression or numeric constant. |
promoted_dim |
The desired dimensions. |
object |
A Promote object. |
values |
A list containing the value to promote. |
arg_objs |
A list of linear expressions for each argument. |
dim |
A vector representing the dimensions of the resulting expression. |
data |
A list of additional data required by the atom. |
to_numeric: Promotes the value to the new dimensions.
is_symmetric: Is the expression symmetric?
dim_from_args: Returns the (row, col) dimensions of the expression.
is_atom_log_log_convex: Is the atom log-log convex?
is_atom_log_log_concave: Is the atom log-log concave?
get_data: Returns information needed to reconstruct the expression besides the args.
graph_implementation: The graph implementation of the atom.
exprAn Expression or numeric constant.
promoted_dimThe desired dimensions.
