Given the array "a.mat" here attached, if I plot it, i.e.
plot(a(:,1),a(:,2))
I get this picture
Instead, if I plot it in a log scale, i.e.
loglog(a(:,1),a(:,2))
I get this picture (it looks like the points are not sorted...)
How to have a smooth curve in the "loglog" plot, where the line connecting the data points does not "jump" back and forth ?

a = sortrows(a,[1 2])
loglog(a(:,1),a(:,2))
