NettetLinear least squares. Curve fitting is the process of finding the curve that best approximates a set of points from within a set of curves. The least squares method does this by minimizing the sum of the squares of the differences between the actual and predicted values. The linear least squares method, which is used here, restricts the set … NettetExample 4.8. Least squares solution for Helmholtz equation. To illustrate the use of a least squares approach consider the Helmholtz problem governed by ... Curve fitting …
