Examples
Code Editor (JavaScript)
print(ee.Array([-6]).erf()); // [-1]
print(ee.Array([0]).erf()); // [0]
print(ee.Array([6]).erf()); // [1]
var start = -3;
var end = 3;
var points = ee.Array(ee.List.sequence(start, end, null, 50));
var values = points.erf();
// Plot erf() defined above.
var chart = ui.Chart.array.values(values, 0, points)
.setOptions({
viewWindow: {min: start, max: end},
hAxis: {
title: 'x',
