Calculates the regularized lower incomplete Gamma function γ(x,a).
| Usage | Returns | Number.gammainc(right) | Number |
| Argument | Type | Details | this: left | Number | The left-hand value. |
right | Number | The right-hand value. |
Examples
Code Editor (JavaScript)
print('Lower incomplete gamma function for x = 0, a = 1',
ee.Number(0).gammainc(1)); // 0
print('Lower incomplete gamma function for x = 1, a = 1',
ee.Number(1).gammainc(1)); // 0.632120558
print('Lower incomplete gamma function for x = 10, a = 1',
ee.Number(10).gammainc(1)); // 0.999954600
print('Lower incomplete gamma function for x = -1, a = 1',
ee.Number(-1).gammainc(1)); // NaN
print('Lower incomplete gamma function for x = 10, a = -1',
ee.Number(10).gammainc(-1)); // NaN
