Uso
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 here -∞ and ∞ represent the smallest negative and largest positive value supported by the particular raster format, respectively.
-
Los valores de entrada y salida en ACosH se interpretan sin unidades.
Output values are always floating point, regardless of the input data type.
Sintaxis
| Parámetro | Explicación | Tipo de datos |
in_raster_or_constant |
La entrada para la cual se calculan los valores del coseno hiperbólico inverso. 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 |
Valor de retorno
| Nombre | Explicación | Tipo de datos |
| out_raster |
The output raster. Los valores son el coseno hiperbólico inverso de los valores de entrada. | Raster |
Ejemplo de código
Este ejemplo calcula el coseno hiperbólico inverso de los valores del ráster GRID de entrada y saca un ráster IMG.
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")
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
# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *
# 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)
# Save the output
outACosH.save("C:/sapyexamples/output/outacosh")
