Can LU decomposition be used for conditional simulation of 2D random field?

We know that LU decomposition is an important method for stochastic simulation of 2D RF. Assume the covariance matrix of regionalized RVs is C, it can be decomposed as C=LU according to the LU...

Can I simulate a random field with nested variogram by a summation of independently simulated random field for each componnet of the nested variogram?

I want to simulate a random field Z(u) that has a nested variogram, say gamma(h)=gamma1(h) + gamma2(h) + gamma3(h), assuming the variogram is isotropic. Whether can I simuate independently three...

Is there fractal simulation algorithm that can condition to known data for 2D case?

There are algorithms, like Diamond-Square method, for generating 2D landscape. I want to meanwhile condition the generated 2D surface to known point data. Is there any published method that can do...
