Geoffrey Fairchild of Los Alamos National Laboratory contributed several
fixes to version 1.1 of sampen.m and cross-sampen.m, which have been
incorporated in version 1.1-1:
* In sampen.m, the line
if ~exist('m')|isempty(m),m=5;end
should be
if ~exist('M')|isempty(M),M=5;end
Geoffrey notes, "The difference is that the M needs to be capitalized.
MATLAB allows this, but it does give a warning. I discovered it when
running SampEn using Octave which threw an error instead of a warning."
* The same error exists in version 1.1 of cross-sampen.m, and the same
correction is applied here.
* In cross_sampen.m, the function declaration (the first line in the file)
function [e,A,B]=cross_sampen(x,y,M,r);
should include a fifth input argument (sflag, as noted in the function's
help comments immediately below the declaration), and it should not end
with a semicolon; the correct declaration is
function [e,A,B]=cross_sampen(x,y,M,r,sflag)
