Reshape-class: The Reshape class.

Description

This class represents the reshaping of an expression. The operator vectorizes the expression, then unvectorizes it into the new dimensions. Entries are stored in column-major order.

Usage

Reshape(expr, new_dim)
# S4 method for Reshape
to_numeric(object, values)
# S4 method for Reshape
validate_args(object)
# S4 method for Reshape
dim_from_args(object)
# S4 method for Reshape
is_atom_log_log_convex(object)
# S4 method for Reshape
is_atom_log_log_concave(object)
# S4 method for Reshape
get_data(object)
# S4 method for Reshape
graph_implementation(object, arg_objs, dim, data = NA_real_)

Arguments

expr

An '>Expression or numeric matrix.

new_dim

The new dimensions.

object

A '>Reshape object.

values

A list of arguments to the atom.

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.

Methods (by generic)

to_numeric: Reshape the value into the specified dimensions.
validate_args: Check the new shape has the same number of entries as the old.
dim_from_args: The c(rows, cols) dimensions of the new 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 a list containing the new shape.
graph_implementation: The graph implementation of the atom.

Slots

expr: An '>Expression or numeric matrix.

new_dim

The new dimensions.
