AI-generated Key Takeaways
-
The
erfcInv()method computes the inverse complementary error function for each element of an input array. -
It takes an array as input and returns an array of the same shape containing the computed values.
-
Examples are provided in both JavaScript and Python demonstrating how to use the
erfcInv()method and visualize its output.
| Usage | Returns |
|---|---|
Array.erfcInv() | Array |
| Argument | Type | Details |
|---|---|---|
this: input | Array | The input array. |

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) .setOptions({ viewWindow: {min: start, max: end}, hAxis: { title: 'x', viewWindowMode: 'maximized', ticks: [ {v: 0}, {v: 1}, {v: 2}] }, vAxis: { title: 'erfcInv(x)', ticks: [ {v: -3}, {v: 0}, {v: 3}] }, lineWidth: 1, pointSize: 0, }); print(chart);
