Description:

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 vm 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.

Does this one work with octave too?

No idea. If you test it, let me know. :)
