範例

程式碼編輯器 (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)
    .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);
