Problem definition
Objective function
f = @(x,b) b(1)-b(2)*x-(atan(b(3)./(x-b(4)))/pi)
Problem setup
Graphic representation
scatter(x,y)
Optimization example with lsqcurvefit
Optimization
rng(0)% for tractability
[b,info] = lsqcurvefit(f,ig1,x,y)% running minimization
Animation
rng(0) [~,info] = lsqcurvefit(f,ig1,x,y) info.plot = 'fit' info.animate = true% plot animation
info.animfreq = 30% frame frequency
optimview('lsqcurvefit',info)
