Hi All,

I was trying to use the function ksdensity, but I got the following error message

    "Error using mad
    Too many input arguments.
    Error in mvksdensity>apply_censoring_get_bandwidth (line 314)
                sig = mad(ty,1,1) / 0.6745;
    Error in mvksdensity (line 91)
    [ty,ymax,weight,u,foldpoint,maxp] = apply_censoring_get_bandwidth(cens,yData,ty,n,ymax,weight,u,d);
    Error in ksdensity (line 222)
        [fout,xout,u,plottype] = mvksdensity(yData,xi,varargin{:});"

I then tried to test whether it is because of mad function, and I did the following:

    "a=mad([1:1:10],1)
    Error using mad
    Too many input arguments."

The ksdensity function works perfect on MATLAB 2015b a few months ago. I didn't change anything in the program since then, but it doesn't work now. Does anyone meet the same problem and know how to fix this? Any suggestions would be much appreciated.

Happy holidays
