p = poisscdf(x, lambda)
p = poisscdf(x, lambda, 'upper')
| Parameter | Description |
|---|---|
| x | real numeric array. |
| lambda | nonnegative rate parameter. |
| Parameter | Description |
|---|---|
| p | cumulative probabilities or upper-tail probabilities. |
poisscdf computes lower-tail Poisson probabilities by default and upper-tail probabilities with 'upper'.
x = 0:10;
p = poisscdf(x, 4);
