Module `Badiff.OrderedBTypeName`Source

Extends BTypeName with comparison operators.

parameter T
module of operators over the underlying type on which we perform automatic differentiation

Parameters

module T : sig ... end

Signature

Sourcetype t

Sourcetype elt = T.elt

Type of values: this is the type that the user should use with make and that will be returned by get

Sourcetype scalar = T.scalar

Type of scalars

Sourceval copy : t -> t

Sourceval deepcopy : t -> t

Constructors

Sourceval create : unit -> t

Sourceval make : elt -> t

Wrap a user-provided value

Sourceval integer : int -> t

Wrap an integer

Sourceval zero : unit -> t

Construct a fresh value corresponding to 0

Sourceval one : unit -> t

Construct a fresh value corresponding to 1

Sourceval two : unit -> t

Construct a fresh value corresponding to 2

Destructors

Sourceval get : t -> elt

Unwrap a value

Sourceval (!!) : t -> elt

Alias for get

Sourceval to_string : t -> string

Sourceval string_of_scalar : scalar -> string

Sourceval string_of_elt : elt -> string

Arithmetic operators

Sourceval (~+) : t -> t

unary plus (with copy)

Sourceval (~-) : t -> t

Sourceval cos : t -> t

Sourceval tan : t -> t

Sourceval asin : t -> t

Sourceval acos : t -> t

Sourceval atan : t -> t

Scalar operators

Sourceval scale : t -> scalar -> t

Multiplication between a value and a scalar

Sourceval translate : t -> scalar -> t

Addition between a value and a scalar

Comparison operators

Sourceval (=) : t -> t -> bool

Sourceval (<>) : t -> t -> bool

Sourceval (<) : t -> t -> bool

Sourceval (<=) : t -> t -> bool

Sourceval (>) : t -> t -> bool

Sourceval (>=) : t -> t -> bool

Sourceval min : t -> t -> t

Sourceval max : t -> t -> t

Operators

Sourcetype op = ..

Sourcetype op +=

| CONST
| SCALE of scalar
| TRANS of scalar
| ADD
| SUB
| MUL
| DIV
| POW
| POS
| NEG
| INV
| SQR
| SQRT
| EXP
| LOG
| SIN
| COS
| TAN
| ASIN
| ACOS
| ATAN

Additionnal constructors

Sourceval lift : T.t -> t

Accessors

Sourceval value : t -> T.t

Same as get but returns an T.t instead of an elt

Automatic Differentiation

Sourceval diff : t -> int -> int -> unit

diff x i n assigns i as index of variable x out of n

Sourceval d : t -> int -> elt

d f i retrieves the derivative of variable of index i in computation f as an elt. Must be called after diff and compute.

Sourceval deriv : t -> int -> T.t

Same as d but returns an T.t instead of an elt

Sourceval compute : t -> unit

compute f updates the reference counter of the nodes in the sub-graph starting from f so that they are propagated at the right moment. Must be called before d or deriv.

Sourceval compute_list : t list -> unit

Same as running compute on each element of the input list.
