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 signature 'Reshape'
to_numeric(object, values)

## S4 method for signature 'Reshape'
validate_args(object)

## S4 method for signature 'Reshape'
dim_from_args(object)

## S4 method for signature 'Reshape'
is_atom_log_log_convex(object)

## S4 method for signature 'Reshape'
is_atom_log_log_concave(object)

## S4 method for signature 'Reshape'
get_data(object)

## S4 method for signature '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.
