(contributed by Paolo Luchini) estimates the mean of a statistically stationary time series simultaneously with a variance of the estimate itself. Its use is to produce a realistic error bar taking into account the statistical error associated with the finite time sampling of an autocorrelated process.

(contributed by Flavio Giannetti) evaluates the eigenvalues of the Orr-Sommerfeld equation with a spectral collocation method using a 3-term recurrence relation to evaluate the derivatives of Chebyshev polynomials and the Fortran interface to call the appropriate lapack subroutine.

(contributed by Paolo Luchini) Reproduction of the historical (Thomas, 1953) compact-difference computation of eigenfunctions and eigenvalues of the Orr-Sommerfeld equation.

(contributed by Paolo Luchini) Toolbox offering a mean turbulent velocity profile as a CPL FUNCTION that can be used for plotting or as a component of your own program.
