(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.
