On an element-wise basis, computes the inverse complementary error function of the input.
| Usage | Returns | Array.erfcInv() | Array |
| Argument | Type | Details | this: input | Array | The input array. |
Examples
Code Editor (JavaScript)
print(ee.Array([0.1]).erfcInv()); // [1.163]
print(ee.Array([1]).erfcInv()); // [0]
print(ee.Array([1.9]).erfcInv()); // [-1.163]
var start = 0.001;
var end = 1.999;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.erfcInv();
// Plot erfcInv() defined above.
var chart = ui.Chart.array.values(values, 0, points)
