Wblpdf

Definition:

$wp = wblpdf(x, a, b)$ returns the probability density function of the Weibull distribution with parameters a and b.

$P(x {\vert}a,b)=ba^{-b}x^{b-1}e^{-(\frac xa)^b}$

$x$ (inptu, double): The value of the x variate. $x\geq 0$
$a$ (inptu, double): The scale parameter, a, of the required Weibull distribution, must be positive( a>0 ).
$b$ (inptu, double): The shape parameter, b, of the required Weibull distribution, must be positive( b> 0)
$wp$ (output, double): The probability.
