L-curve analysis function.
Syntax
lam_opt=lcurve(lam,err,reg,mode)
Arguments
lam - row vector of regularisation parameters
err - row vector of least squares errors
reg - row vector of regularisation functional values
mode - 'log' for logarithmic coordinates and 'linear'
for linear ones; 'log' is recommended
The function returns the regularisation parameter at the point of the maximum curvature of the L-curve.
