y = lognpdf(x)
y = lognpdf(x, mu)
y = lognpdf(x, mu, sigma)
| Parameter | Description |
|---|---|
| x | real scalar or array: values. |
| mu | real scalar or array: mean of logarithmic values. The default is 0. |
| sigma | positive scalar or array: standard deviation of logarithmic values. The default is 1. |
| Parameter | Description |
|---|---|
| y | array: density values. |
lognpdf evaluates lognormal probability density values element by element.
Scalar parameters are expanded to match array inputs.
x = [0 1 exp(1)];
