+## Contents:
+- `circ_r` 				Resultant vector length
+- `circ_mean` 			Mean direction of a sample of circular data
+- `circ_axial`			Mean direction for axial data
+- `circ_median`			Median direction of a sample of circular data
+- `circ_std` 			Dispersion around the mean direction (std, mardia)
+- `circ_var` 			Circular variance
+- `circ_skewness`		Circular skewness
+- `circ_kurtosis`		Circular kurtosis
+- `circ_moment`			Circular p-th moment
+- `circ_dist`			Distances around a circle
+- `circ_dist2`			Pairwise distances around a circle
+- `circ_confmean` 		Confidence intervals for mean direction
+- `circ_stats`			Summary statistics
+
+ 
+- `circ_rtest`			Rayleigh's test for nonuniformity
+- `circ_otest`			Hodges-Ajne test (omnibus test) for nonuniformity
+- `circ_raotest`		Rao's spacing test for nonuniformity
+- `circ_vtest`			V-Test for nonuniformity with known mean direction
+- `circ_medtest`		Test for median angle
+- `circ_mtest`			One-sample test for specified mean direction
+- `circ_wwtest`			Multi-sample test for equal means, one-factor ANOVA
+- `circ_hktest` 		Two-factor ANOVA
+- `circ_ktest`      	Test for equal concentration parameter
+- `circ_symtest`		Test for symmetry around median angle
+- `circ_kuipertest`	 	Test whether two distributions are identical (like KS test)
+
+ 
+- `circ_corrcc`			Circular-circular correlation coefficient
+- `circ_corrcl`			Circular-linear correlation coefficient
+
+ 
+- `circ_kappa` 			Compute concentration parameter of a von Mises distribution
+- `circ_plot`			Visualization for circular data
+- `circ_clust`    		Simple clustering for circular data
+- `circ_samplecdf`	 	Evaluate CDF of a sample of angles
+
+ 
+- `rad2ang`				Convert radian to angular values
+- `ang2rad`				Convert angular to radian values
+
+All functions take arguments in radians (expect for `ang2rad`). For a detailed description of arguments and outputs consult the help text in the files.
+
+Since 2010, most functions for descriptive statistics can be used in Matlab style matrix computations. As a last argument, add the dimension along which you want to average. This changes the behavior slightly from previous relaeses, in that input is not reshaped anymore into vector format. Per default, all computations are performed columnwise (along dimension 1). If you prefer to use the old functions, for now they are contained in the subdirectory 'old'.

+The implementation follows in most cases 'Biostatistical Analysis' and all referenced equations and tables are taken from this book, if not otherwise noted. In some cases, the other books were preferred for implementation was more straightforward for solutions presented there.

+## Disclaimer:
+All functions in this toolbox were implemented with care and tested on the examples presented in 'Biostatistical Analysis' were possible. Nevertheless, they may contain errors or bugs, which may affect the outcome of your analysis. We do not take responsibility for any harm coming from using this toolbox, neither if it is caused by errors in the software nor if it is caused by its improper application. Please email us any bugs you find.
