SumEntries-class function

The SumEntries class.

This class represents the sum of all entries in a vector or matrix. class

SumEntries(expr, axis = NA_real_, keepdims = FALSE)

## S4 method for signature 'SumEntries'
to_numeric(object, values)

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

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

## S4 method for signature 'SumEntries'
graph_implementation(object, arg_objs, dim, data = NA_real_)

Arguments

• expr: An Expression representing a vector or matrix.
• axis: (Optional) The dimension across which to apply the function: 1 indicates rows, 2 indicates columns, and NA indicates rows and columns. The default is NA.
• keepdims: (Optional) Should dimensions be maintained when applying the atom along an axis? If FALSE, result will be collapsed into an $n x 1$ column vector. The default is FALSE.
• object: A SumEntries 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(SumEntries): Sum the entries along the specified axis.
• is_atom_log_log_convex(SumEntries): Is the atom log-log convex?
• is_atom_log_log_concave(SumEntries): Is the atom log-log concave?
• graph_implementation(SumEntries): The graph implementation of the atom.
