Reshape-class function

The Reshape class.

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. class

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.
