% FEATURES of the NaN-tb:
% -----------------------
%  - implements statistical tools
%  - NaN's are treated as missing values 
%  - less but more powerful functions (no nan-FUN needed)
%  - fixes known bugs 
%  - compatible to Matlab and Octave
%  - easy to use
%  - supports DIM argument 
%  - supports unbiased estimation; 
%  - The toolbox was tested with
%    Matlab 5.2, 5.3, 6.1, 6.5 and Octave 2.0.14, 2.0.16.92, 2.1.35-40, 2.1.50
% 
%  
% Currently are implemented:
% -------------------------- 
% 	SUMSKIPNAN 	SUM is a built-in function and cannot not be replaced, 
% 			For this reason, a different name (than SUM) had to be chosen. 
% 			SUMSKIPNAN is central, it implements skipping NaN's, the 
% 			DIM-argument and returns the number of valid elements, too.
% 	MEAN	 	mean (options: arithmetic, geometric, harmonic)
% 	SEM		standard error of the mean (does not depend on distribution)
% 	VAR 		variance
% 	STD 		standard deviation
% 	MEDIAN		median (currently only for 2-dim matrices)
% 	MEANSQ		mean square
% 	RMS		root mean square
% 	STATISTIC	estimates various statistics at once
% 	MOMENT		moment 	
% 	SKEWNESS	skewness
% 	KURTOSIS	excess 
% 	MAD		mean absolute deviation
% 	CENTER		removes mean
% 	ZSCORE		normalizes x with z = (x-mean)/std 
% 	HARMMEAN	harmonic mean
% 	GEOMEAN		geometric mean
% 	NANTEST		checks whether all functions have been replaced
% 	DETREND		detrending of data with missing values and non-equidistant sampled data
% 	COVM		covariance estimation (several modes)
% 	COR		correlation matrix
% 	CORRCOEF	correlation coefficient, inluding rank correlation, 
% 				significance test and confidence intervals 
% 	SPEARMAN, RANKCORR spearman's rank correlation coefficient. They might be replaced by CORRCOEF. 
% 	COV		covariance matrix
% 	RANKS		calculates ranks for non-parametric statistics 
% 	TRIMEAN		trimean
% 	QUANTILE	q-th quantile 
% 	PERCENTILE	p-th percentile
% 	NORMPDF		normal probability distribution
% 	NORMCDF		normal cumulative distribution 
% 	NORMINV		inverse of the normal cumulative distribution
% 	TPDF		student probability distribution
% 	TCDF		student cumulative distribution 
% 	TINV		inverse of the student cumulative distribution
% 	NANSUM, NANSTD	fixes for buggy versions included
