Arguments

expr

An '>Expression.

axis

A numeric vector indicating the axes along which to apply the function. For a 2D matrix, 1 indicates rows, 2 indicates columns, and c(1,2) indicates rows and columns.

object

A '>CumMax object.

values

A list of numeric values for the arguments

value

A numeric value.

idx

An index into the atom.

Methods (by generic)

  • to_numeric: The cumulative maximum along the axis.

  • .grad: Gives the (sub/super)gradient of the atom w.r.t. each variable

  • .column_grad: Gives the (sub/super)gradient of the atom w.r.t. each column variable

  • dim_from_args: The dimensions of the atom determined from its arguments.

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

  • get_data: Returns the axis along which the cumulative max is taken.

  • is_atom_convex: Is the atom convex?

  • is_atom_concave: Is the atom concave?

  • is_incr: Is the atom weakly increasing in the index?

  • is_decr: Is the atom weakly decreasing in the index?

Slots

expr

An '>Expression.

axis

A numeric vector indicating the axes along which to apply the function. For a 2D matrix, 1 indicates rows, 2 indicates columns, and c(1,2) indicates rows and columns.
