ee.Number.gammainc

  • TheNumber.gammainc method calculates the regularized lower incomplete Gamma function γ(x,a) and returns a Number.

  • It takes two Number arguments:this (the left-hand value) andright (the right-hand value).

  • The function returns NaN for negative input values for either x or a.

  • Examples demonstrate its usage in both JavaScript and Python.

 Calculates the regularized lower incomplete Gamma function γ(x,a).

UsageReturns
Number.gammainc(right)Number
ArgumentTypeDetails
this:leftNumberThe left-hand value.
rightNumberThe right-hand value.
