GoldenSection
In mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant, approximately 1.6180339887.[1] Other names frequently used for the golden ratio are the golden section (Latin: sectio aurea) and golden mean.[2][3][4] Other terms encountered include extreme and mean ratio,[5] medial section, divine proportion, divine section (Latin: sectio divina), golden proportion, golden cut,[6] golden number, and mean of Phidias.[7][8][9] The golden ratio is often denoted by the Greek letter phi, usually lower case (φ).

说明: 此程序用提升法实现第二代小波变换
我用的是非整数阶小波变换
采用时域实现,步骤先列后行
正变换:分裂,预测,更新;
反变换:更新,预测,合并
只做一层(可以多层,而且每层的预测和更新方程不同)(procedure used to upgrade Method second generation wavelet transform I use a non-integer-order wavelet transform domain when used, the first step out go backward transformation : split and forecast updates; Anti-Transform : Update, forecasting, consolidations only one (which can be multi-storey, but each floor and update the forecast equation different))

PV_System
Incremental Conductance: In the incremental conductance algorithm, we find the derivative of PV output power
with respect to output voltage. The dP/dV is evaluated and the algorithm keeps checking this value and changes
the duty cycle such that dP/dV=- I/V = 0. This is the point at which maximum power is transferred. If dP/dV is
greater than zero, it means the PV is operating to the left of the MPP. If dP/dV is less than zero, it means the PV is
operating to the right of the MPP. This method holds an advantage over the perturb and observe method since it is
fast and does not oscillate around MPP. However, the method could experience instability due the involvement of
the derivative.

设有离散无记忆信源X,P(X).二进制费诺编码为:1.将信源符号按概率从大到小的顺序排列2.将信源分成两组――按两组概率之差为最小分.3.上面一组编码为0,下面一组编码为1,一直分到一组只有一个信源为止.4.将一个信源分组得到的0和1全部连接起来,组成该信源的码字,信源即得到自己的费诺编码.(There be no X remembering the message source in case that having being scattered, binary Feinuo of P (X) code is: 1. Will believe that the source sign orders 2 according to probability is minor from arriving at greatly sequence. Will believe that the source divides into two part being allotted 3 according to two set of bad of probability for the minimum. A group of code is 0 above , a group of code is 1 underneath, till dividing till a group only when one believes a source 4. Get up with a 0 and 1 all connection believing that the source is divided into groups and , be composed of the codon owing message a source , believe that the source is to get self Feinuo code
