Summary
Calculates the inverse hyperbolic cosine of cells in a raster.
Illustration
Usage
In mathematics, all trigonometric functions have a defined range of valid input values, called the domain. The output values from each function also has a defined range. For this tool
The Domain is : 1 ≤ [in_value] < ∞
Note that any input value that is outside this domain will receive NoData on the output raster.
The Range is : -∞ < [out_value] < ∞
Note that -∞ and ∞ represent the smallest negative and largest positive value supported by the particular raster format, respectively.
The input and output values for this tool are interpreted as unitless.
Output values are always floating point, regardless of the input data type.
If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.
Syntax
ACosH(in_raster_or_constant)
Parameter | Explanation | Data Type |
in_raster_or_constant | The input for which to calculate the inverse hyperbolic cosine values. 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
Name | Explanation | Data Type |
out_raster | The output raster. The values are the inverse hyperbolic cosine of the input values. | Raster |
Code sample
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.ia import *
env.workspace = "C:/iapyexamples/data"
outACosH = ACosH("degs")
outACosH.save("C:/iapyexamples/output/outacosh.img")
This example calculates the inverse hyperbolic cosine of the values in the input Grid raster.
