Histograms

type t = private {
n : int;

(** number of histogram bins *)

range : float array;

(** ranges of the bins ; n+1 elements *)

bin : float array;

(** counts for each bin ; n elements *)

}

The histogram type

val check : t ‑> bool

Allocating histograms

val make : int ‑> t
val copy : t ‑> t
external set_ranges : t ‑> float array ‑> unit = "ml_gsl_histogram_set_ranges"
external set_ranges_uniform : t ‑> xmin:float ‑> xmax:float ‑> unit = "ml_gsl_histogram_set_ranges_uniform"

Updating and accessing histogram elements

external accumulate : t ‑> ?⁠w:float ‑> float ‑> unit = "ml_gsl_histogram_accumulate"
val get : t ‑> int ‑> float
val get_range : t ‑> int ‑> float * float
val h_max : t ‑> float
val h_min : t ‑> float
val bins : t ‑> int
val reset : t ‑> unit

Searching histogram ranges

external find : t ‑> float ‑> int = "ml_gsl_histogram_find"

Histograms statistics

external max_val : t ‑> float = "ml_gsl_histogram_max_val"
external max_bin : t ‑> int = "ml_gsl_histogram_max_bin"
external min_val : t ‑> float = "ml_gsl_histogram_min_val"

external mean : t ‑> float = "ml_gsl_histogram_mean"
external sigma : t ‑> float = "ml_gsl_histogram_sigma"
external sum : t ‑> float = "ml_gsl_histogram_sum"

Histogram operations

external equal_bins_p : t ‑> t ‑> bool = "ml_gsl_histogram_equal_bins_p"
external add : t ‑> t ‑> unit = "ml_gsl_histogram_add"
external sub : t ‑> t ‑> unit = "ml_gsl_histogram_sub"

Resampling

type histo_pdf = private {
pdf_n : int;
pdf_range : float array;
pdf_sum : float array;
}
val init : t ‑> histo_pdf
external sample : histo_pdf ‑> float ‑> float = "ml_gsl_histogram_pdf_sample"
