Description: 等值线
在科学计算和现实生活中，常常会遇到y=f(t)这类函数关系，例如，正弦、余弦等等。函数y=f(t)往往是以离散的观测值形式f(ti)(i=1,....N)表现出来的。例如，令股民朋友如醉如痴的K线图，与千家万户性命攸关的河流水位曲线图等等。离散函数关系有不少数据处理课题，例如，数据拟合、插值和平滑等等。最令人兴奋的还是预测，如果股民朋友能够准确把握y=f(t)的走向，钞票就会源源不断涌入口袋。如果水文学家能够准确预测河流水位暴涨的过程，可以大量减少生命和财产损失。
所谓画曲线就是描绘y=f(t)的图象，在本书我们将通过图象绘制直观地了解观测值的变化和数据处理方法的效果-contours in scientific computing and real-life, we will often encounter y = f (t) such a function, such as sine, cosine and so on. Function y = f (t) tend to be discrete observation form f (t) (i = 1 ...... N) the performance. For example, investors simply friends of K map, and the millions of lives at stake curve of water levels in rivers and so on. Discrete function of a number of data-processing tasks, such as data fitting, interpolation and smoothing and so on. Most exciting is predicted that if shareholders friends to accurately grasp y = f (t) trend, money will continue to flood into pockets. If hydrologists can accurately predict river levels rose process, a significant reduction in loss of life and property.

Description: 曲线拟合涉及回答两个基本问题: 最佳拟合意味着什么？应该用什么样的曲线？可用许多不同
的方法定义最佳拟合, 并存在无穷数目的曲线. 所以, 从这里开始, 我们走向何方？正如它证实的那
样, 当最佳拟合被解释为在数据点的最小误差平方和, 且所用的曲线限定为多项式时, 那么曲线拟
合是相当简捷的.-Curve fitting involves answering two fundamental questions: What does it mean for the best fit? What should be the kind of curve? Available in many different ways to define the best fitting, and the existence of infinite number of curves. So, from here on, we going? As it proved, when the best fit is interpreted as data points in the smallest error sum of squares, and used to be limited to polynomial curve, then curve fitting is very simple. Platform: |
