Sampling of 1D and 2D pseudo random curves and fields.
The algorithm is the one derived in Evensen (1994, 2003, 2004) for the generation of the pseudo random fields and the improved sampling.
However, the latest verison avoids the use of the newton solver by giving analytic expressions for r1=sqrt(3)/rx and ry=sqrt(3)/ry
We have decided to use the FFTW3 library which is available for many unix systems from http://www.fftw.org/

git clone [email protected]:geirev/EnKF_sampling.git
cd EnKF_sampling/lib
make
To test:
