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
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

pca, pc Principle component analysis 'pcacov' if likely the equivalent pca - C, pc - FORTRAN
poincare Create Poincaré sections
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
polynom Fit a polynomial model same as above same as above
