In reference to the TISEAN library alphabetical order of programs which is located here.

Program Name Program Description Corresponding Octave Function Comments
arima-model Fit and possibly iterate an ARIMA model There is 'aar' in TSA but cannot determine if this is different or not This is a c-file that can be wrapped in C++/mfile/octfile code
ar-model Fit and possibly iterate an Autoregessive model Same as above C; see also: aarmam, adim, amarma, mvaar from TSA
ar-run Iterate an Autoregessive model Same as above FORTRAN
av-d2 Simply smooth output of d2 Same as above C
boxcount Renyi Entopies of Qth order There most likely is none C
c1 Fixed mass estimation of D1 Most likely is none FORTRAN
c2d Get local slopes from correlation integral Most likely none FORTRAN
c2g Gaussian kernel of C2 Does not exist FORTRAN
c2t Takens estimator of D2 Most likely 'rmle' from tsa FORTRAN
choose Choose rows and/or columns from a data file Does not need to be ported ------
compare Compares two data sets If 'rms' exists in Octave no need for port FORTRAN
corr, autocorr Autocorrelation function There is 'acorf' in tsa but i don't know if is the same corr -C, autocorr (faster according to documentation) - FORTRAN
d2 Correlation dimension d2 I believe not, don't know c
delay Creates delay embedding Most likely does not exist C
endtoend Determine end-to-end mismatch Does not exist FORTRAN
events Interval/event conversion Might exist, most likely does not FORTRAN to be implemented as mfile

false_nearest The false nearest neighbor algorithm Does not exist C
ghkss Nonlinear noise reduction There is not C
henon Create a Hénon time series There is not To m-file; already ported
histogram Creates histograms Might exist, cannot find(obviously histogram exists, but I cannot tell if it "estimates the scalar distribution of data set") C
ikeda Create an Ikeda time series Does not exist FORTRAN to be reimplemented as mfile
intervals Event/intervcal conversion Might exist under different name FORTRAN to be reimplemented as mfile
lazy Simple nonlinear noise reduction There is not FORTRAN

lorenz Create a Lorenz time series Does not exist FORTRAN
low121 Time domain low pass filter There are lowpass filters in Octave: buttap, cheb1ap, cheb2ap, ellipap, sftrans, but I don't think they perform this task C, might be ok to implement as mfile
lyap_k Maximal Lyapunov exponent with the Kantz algorithm Does not exist C
lyap_r Maximal Lyapunov exponent with the Rosenstein algorithm Does not exist C
lyap_spec Full spectrum of Lyapunov exponents Does not exist C

mutual Estimate the mutual information Does not exist C
notch Notch filter pei_tseng_notch, needs to be verified FORTRAN
nstat_z Nonstationarity testing via cross-prediction Does not exist C
pca, pc Principle component analysis 'pcacov' if likely the equivalent pca - C, pc - FORTRAN
poincare Create Poincaré sections Does not exist C
polyback Fit a polynomial model (backward elimination) polyfit, detrend, wpolyfit I do not know if they work the same way, but it does seem so, written in C
