ee.Array.erf

  • TheArray.erf() method computes the error function of each element in the input array.

  • This method takes an Array as input and returns an Array as output.

  • Examples are provided in both JavaScript and Python, demonstrating how to use theerf() method and visualize the results.

 On an element-wise basis, computes the error function of the input.

UsageReturns
Array.erf()Array
ArgumentTypeDetails
this:inputArrayThe input array.

Examples

Code Editor (JavaScript)
