Wblinv

Definition:

xp = w b l i n v (p, a, b) computes the inverse Weibull cumulative distribution function for the given probability using the parameters a and b.

The inverse of the Weibull cdf is

x_p=[aln(\frac 1{1-p}]^{(\frac 1b)}I_{[0,1]}(p)

Parameters:

p (input, double)
The probability,0 < p < 1.
a (input, double)
The scale parameter, a, of the required Weibull distribution, must be positive(a > 0.0).
b (input, double)
The shape parameter, b, of the required Weibull distribution, must be positive (b > 0.0).
xp (output, double)
The value of the variate,x_p
