stats_dens_uniform — Probability density function of the uniform distribution
说明
stats_dens_uniform
( float
$x
, float $a
, float $b
) : float
Returns the probability density at x, where the
random variable follows the uniform distribution of which the lower bound is
a and the upper bound is b.
参数
-
x -
The value at which the probability density is calculated
-
a -
The lower bound of the distribution
-
b -
The upper bound of the distribution
返回值
