ee.Array.erfc

  • Array.erfc() calculates the complementary error function for each element in an input array.

  • The function returns a new array with the calculated complementary error function values.

  • It operates on an element-by-element basis, applying the erfc function to each value in the input array.

  • Usage examples are provided in both JavaScript and Python to demonstrate the function's application.

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

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

Examples

Code Editor (JavaScript)

print(ee.Array([-6]).erfc());  // [2]
print(ee.Array([0]).erfc());  // [1]
print(ee.Array([28]).erfc());  // [0]

var start = -3;
var end = 3;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.erfc();

// Plot erfc() defined above.
var chart = ui.Chart.array.values(values, 0, points)
