Reshape-class {CVXR}

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): Reshape the value into the specified dimensions.

• validate_args(Reshape): Check the new shape has the same number of entries as the old.

• dim_from_args(Reshape): The c(rows, cols) dimensions of the new expression.

• is_atom_log_log_convex(Reshape): Is the atom log-log convex?

• is_atom_log_log_concave(Reshape): Is the atom log-log concave?

• get_data(Reshape): Returns a list containing the new shape.

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

Slots

expr

An Expression or numeric matrix.

new_dim

The new dimensions.
