[Scilab-users] needed: SciLab routine for generating Weibull random variables with prior given autocorrelation

[Heinz Nabielek]

Friends:

urgently needed: a SciLab routine for generating Weibull random variables with prior given autocorrelation.

Uncorrelated is easy with 
vc*((-log(grand(1,5,"def"))).^(1/m)) producing
0.9666848   1.4646143   10.402793   5.9513675   3.3241823
with characteristic velocity vc=7 and modulus m=2.

But I need Weibull deviates with given autocorrelation, say rho=0.80

Literature has dozen of references on the subject which either do not work or I do not know how to code.

Any help here?
