When trying to smooth the graph at the end, some kind of error occurs in its construction.
%a=(1+rand(1,size(x,2))).*10^-5; % this code makes my values ​​unique
%b=(1+rand(1,size(x,2))).*10^-5;
%x=x+a;
%y=y+b;
yy1 = smooth(x,y,0.1,'loess'); % with a value of 0.1 I like the beginning of the graph
plot(x,y,'b.',x,yy1,'r-') % when using "rloess" same error
Thank you in advance.

What error? You should copy/paste all error messages.

"x" is not monotonous, therefore, you should use this kind of form:
yy1 = smooth(y,0.1,'loess');
