The CumMax class.
This class represents the cumulative maximum of an expression.
CumMax(expr, axis = 2) ## S4 method for signature 'CumMax' to_numeric(object, values) ## S4 method for signature 'CumMax' .grad(object, values) ## S4 method for signature 'CumMax' .column_grad(object, value) ## S4 method for signature 'CumMax' dim_from_args(object) ## S4 method for signature 'CumMax' sign_from_args(object) ## S4 method for signature 'CumMax' get_data(object) ## S4 method for signature 'CumMax' is_atom_convex(object) ## S4 method for signature 'CumMax' is_atom_concave(object) ## S4 method for signature 'CumMax' is_incr(object, idx) ## S4 method for signature 'CumMax' is_decr(object, idx)
expr |
An Expression. |
axis |
A numeric vector indicating the axes along which to apply the function. For a 2D matrix, |
object |
A CumMax object. |
values |
A list of numeric values for the arguments |
value |
A numeric value. |
idx |
An index into the atom. |
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?
