lagrange插值
在节点上给出节点基函数,然后做基函数的线性组合,组合系数为节点函数值,这种插值多项式称为拉格朗日插值公式线性插值也叫两点插值,已知函数y = f (x)在给定互异点x0, x1上的值为y0= f (x0),y1=f (x1)线性插值就是构造一个一次多项式P1(x) = ax + b使它满足条件P1 (x0) = y0 P1 (x1) = y1其几何解释就是一条直线,通过已知点A (x0, y0),B(x1, y1)。线性插值计算方便、应用很广,但由于它是用直线去代替曲线,因而一般要求[x0, x1]比较小,且f(x)在[x0, x1]上变化比较平稳,否则线性插值的误差可能很大。为了克服这一缺点,有时用简单的曲线去近似地代替复杂的曲线,最简单的曲线是二次曲线,用二次曲线去逼近复杂曲线的情形。

DTMF(Dual Tone Multi Frequency)Recognition Algorithm
Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.
While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for
