Arguments

e1, e2

The '>Expression objects or numeric constants to subtract.

object

A '>NegExpression object.

idx

An index into 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)

  • dim_from_args: The (row, col) dimensions of the expression.

  • sign_from_args: The (is positive, is negative) sign of the expression.

  • is_incr: The expression is not weakly increasing in any argument.

  • is_decr: The expression is weakly decreasing in every argument.

  • is_symmetric: Is the expression symmetric?

  • is_hermitian: Is the expression Hermitian?

  • graph_implementation: The graph implementation of the expression.
