Oksana Soshko,Yuri Merkuryev,Martins Chaksteom ballistic to diffusive motion is investigated by calculating the velocity autocorrelation and the mean square displacement. In the second example we apply the Monte Carlo method to the one- and two-dimensional Ising model. A chain of configurations is constructed and the average magnetization is compared to analytical solutions.

Multivariate interpolation is a necessary tool to process multidimensional data sets, for instance, for image processing. A computer experiment compares bilinear interpolation and bicubic spline interpolation.

Oksana Soshko,Yuri Merkuryev,Martins Chaksteations directly. Another important method applies singular value decomposition to reduce redundancies and to extract the most important information from experimental data. An example for linear approximation is shown. A computer experiment demonstrates the least square fit for a typical physical problem.
