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 shape. Entries are stored in column-major order.

Usage

Reshape(expr, rows, cols)
# S4 method for Reshape
validate_args(object)
# S4 method for Reshape
to_numeric(object, values)
# S4 method for Reshape
size_from_args(object)
# S4 method for Reshape
get_data(object)
# S4 method for Reshape
graph_implementation(object, arg_objs, size,
  data = NA_real_)

Arguments

expr

An '>Expression or numeric matrix.

rows

The new number of rows.

cols

The new number of columns.

object

A '>Reshape object.

values

A list of arguments to the atom.

arg_objs

A list of linear expressions for each argument.

size

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)

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

• to_numeric: Reshape the value into the specified dimensions.

• size_from_args: The c(rows, cols) of the new expression.

• get_data: Returns list(rows, cols).

• graph_implementation: The graph implementation of the atom.

Slots

expr

An '>Expression or numeric matrix.

rows

The new number of rows.

cols

The new number of columns.
