I want to fint those scatter points to a curve.
I tried using lsline but seems not working, i tried also with polyfit.
here my small code
clc, clear all;
x = [0,0.1, 0.2, 0.3, 0.4, 0.46, 0.55, 0.6];
y =[0, 0.0982,	0.1359,	0.126,	0.0778,	0.0827,	0.063,	0.0599];
% f= polyfit(y,x,7)
% xx = linspace(min(x), max(x));
% %xx = 0:0.1:2.5;  %%%%%%%%%%%%%%%%%%%%%%
% v = polyval(f, xx); %%%%%%%%%%%%%%%%%%%
% plot(x,y,'o', xx,v,'-')
plot (x,y)
lsline
