Encountering same issue as Shiquan

This is great work! Thanks.

Good work! So far it helped me a lot. But there are some
errors arround!

1.) function circ_hktest

Line 55 found -> qm = zeros(p,1); qr = qm; qn = pm;
   corrected? -> qm = zeros(p,1); qr = qm; qn = qm;

Line 94 found -> eff_2 = sum(qr.^2 ./ sum(cn,2)) - tr.^2/n;
   corrected? -> eff_2 = sum(qr.^2 ./ sum(cn,1)') - tr.^2/n;

Line 107 found -> beta = 1/(1-1/(5*kk)-1/(10*(kk^2)));
       comment -> beta overloads the beta function (help beta)
                  An other name like betaF should be used

Line 144 found -> F1 = beta * ms_1 / ms_r;
       comment -> if inter is set to 0/false beta is not defined!
       
       
2.) function circ_std

The documentation in the paper

  In CircStat , theangular deviation is computed as
  >>s=circ_std(alpha);
  and the circular standard deviation as
  >>s0=circ_std(alpha,[],[],'mardia');
  
does not fit with neither - paper and Matlab Central - implementation.

Sorry, but I think circ_var returns s = (1-r) when it should be s = 2*(1-r).

for this reason, circ_std and circ_var will not agree

Excellent toolbox, helped me a lot. Greatly appreciated!

PS:
I think there is an error in the circ_dist function

I think this

r = angle(repmat(exp(1i*x(:)'),length(y),1) ...
       ./ repmat(exp(1i*y(:)),1,length(x)));

Let me know if it's correct

I take that back -- guilty of confusing 'r' and 'R'

Would include skewness and kurtosis!

thanks.
