type t

val create : (key * value) list ->
       t Core_kernel.Std.Or_error.t

create enforces that x (key) values are non-decreasing.

It also enforces certain finiteness conditions: the x and y values must be finite (non-nan, and non-infinite), and differences of consecutive x values and consecutive y values must be finite.

val get : t ->
       key -> value

get t x evaluates the piecewise linear function t at x.

It is possible to get discontinuous functions by using repeated x-values in the knots. In that case, the function is evaluated in such a way that it is right-continuous. For example, if t has knots [(0.,0.5); (1.,1.5); (1.,10.); (2.,11.)], then get t 1. returns 10., get t 0.999 returns 1.499, and get t 1.001 returns 10.001.

create enforces that x (key) values are non-decreasing.

It also enforces certain finiteness conditions: the x and y values must be finite (non-nan, and non-infinite), and differences of consecutive x values and consecutive y values must be finite.

get t x evaluates the piecewise linear function t at x.
