ee.Array.erfc

  • The Array.erfc() method computes the complementary error function for each element in an input array and returns an array.

 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)
    .setOptions({
      viewWindow: {min: start, max: end},
      hAxis: {
        title: 'x',
        viewWindowMode: 'maximized',
        ticks: [
          {v: start},
          {v: 0},
          {v: end}]
      },
      vAxis: {

        ticks: [
