Total Least Squares Method by Ivo Petras

Mathematical method known as total least squares or orthogonal regression or error-in-variables. (total least squares, svd, errorinvariables)

[Err, min_param]=numerFminD(fun, p, LBa, UBa, xdata, ydata,...

[Err, min_param]=numerFminS(fun, p, LBa, UBa, xdata, ydata)

[F, Srez, Scel]=statindexes(XData, YData, a, b)
