ACosH (Spatial Analyst)

Summary

Calculates the inverse hyperbolic cosine of cells in a raster.

Illustration

OutRas = ACosH(InRas)

Usage

Syntax

ACosH (in_raster_or_constant)
ParameterExplanationData Type
in_raster_or_constant

The input for which to calculate the inverse hyperbolic cosine values.

In order to use a number as an input for this parameter, the cell size and extent must first be set in the environment.

Raster Layer | Constant

Return Value

NameExplanationData Type
out_raster

The output raster.

The values are the inverse hyperbolic cosine of the input values.

Code Sample

ACosH example 1 (Python window)

This example calculates the inverse hyperbolic cosine of the values in the input GRID raster and outputs an IMG raster.

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outACosH = ACosH("degs")
outACosH.save("C:/sapyexamples/output/outacosh.img")
ACosH example 2 (stand-alone script)

This example calculates the inverse hyperbolic cosine of the values in the input GRID raster.

# Name: ACosH_Ex_02.py
# Description: Calculates the inverse hyperbolic cosine of cells
#              in a raster
# Requirements: Spatial Analyst Extension
# Author: ESRI

# Import system modules
import arcpy

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Set local variables
inRaster = "degs"

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

# Execute ACosH
outACosH = ACosH(inRaster)
