NettetLeast Squares Definition. Least squares, in general, is the problem of finding a vector x that is a local minimizer to a function that is a sum of squares, possibly subject to some constraints: min x ‖ F ( x) ‖ 2 2 = min x ∑ i F i 2 ( x) such that A·x ≤ b, Aeq·x = beq, lb ≤ x ≤ ub. There are several Optimization Toolbox™ solvers ... NettetLeast-square method is the curve that best fits a set of observations with a minimum sum of squared residuals or errors. Let us assume that the given points of data are (x 1, y …
