This directory contains utility for implementing generic Reqursive Least Squares (RLS) algorithm. The example shows how one can use the utility to estamate the parameters of a simple linear discrete time system.

The module LSQ is for unconstrained linear least-Squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become available. The module contains a test for singularities which is simpler and quicker than calculating the singular-value decomposition. An important feature of the algorithm is that it does not square the condition number. The matrix X X is not formed. Hence it is suitable for ill- conditioned problems, such as fitting polynomials. By taking advantage of the MODULE facility, it has been possible to remove many of the arguments to routines. Apart from the new function VARPRD, and a back-substitution routine BKSUB2 which it calls, the routines behave as in AS 274.

最小平方近似法 (least-Squares approximation) 是用來求出一組離散 (discrete) 數(shù)據(jù)點(diǎn)的近似函數(shù) (approximating function)，作實(shí)驗(yàn)所得的數(shù)據(jù)亦常使用最小平方近似法來達(dá)成曲線密合 (curve fitting)。以下所介紹的最小平方近似法是使用多項(xiàng)式作為近似函數(shù)，除了多項(xiàng)式之外，指數(shù)、對數(shù)方程式亦可作為近似函數(shù)。關(guān)於最小平方近似法的計算原理，請參閱市面上的數(shù)值分析書籍

多項(xiàng)式曲線擬合 任意介數(shù) Purpose - Least-Squares curve fit of arbitrary order working in C++ Builder 2007 as a template class, using vector<FloatType> parameters. Added a method to handle some EMathError exceptions. If do NOT want to use this just call PolyFit2 directly. usage: Call PolyFit by something like this. CPolyFit<double> PolyFitObj double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A) where X and Y are vectors of doubles which must have the same size and A is a vector of doubles which must be the same size as the number of coefficients required. returns: The correlation coefficient or -1 on failure. produces: A vector (A) which holds the coefficients.

北京大學(xué)ACM題 Here is a geometric problem. You have an angle and some Squares in the first quadrant of the plane rectangular coordinates. The vertex of the angle is fixed on the origin O of the coordinates, and both of its radial lines are specified by the input. The sizes of the Squares are also specified by the input, and the Squares can shift vertically and horizontally. Now your job is to use the Squares and the radial lines of the angle to enclose the maximum area, which excludes the area of the Squares (see Figure 1). You should note that the edges of the Squares must be parallel to the axes.
