amplitude also represents the wave energy, we will call these two arrays as the wave energy buffer. The water surface is a plane in the initial state, and the amplitude of each point is 0. Therefore, the initial values of these two arrays are equal to 0.
The formula for calculating the amplitude is derived below.
Assume that such a formula exists, you can calculate the amplitude of a point at any time based on the four points around a point, namely, the front, the back, the left, and the ri

Python KMeans clustering problem analysis, kmeans Clustering
Today, python is used to implement simple cluster analysis. By the way, I am familiar with some numpy Array Operations and plotting techniques. Here I will record it.
From pylab import * from sklearn. cluster import KMeans # Use numpy. the append () function is used to merge multi-dimensional arrays in matlab. If the axis parameter value is 0, the y axis is merged. If the parameter value is 1, the x axis is merged, correspond to the ef

Rectangle bounding Box algorithm: detects whether 2 rectangles overlap, in such a case to determine whether 2 rectangles collide only need to compare the coordinates of two rectangle vertices. Assuming that rectangle A is used (X1,Y1) for the upper-left corner, (x2,y2) for the lower-right corner, and Rectangle B (x3,y3) for the upper-left corner, (X4,Y4) for the lower-right corner, the following conditions are true to indicate no collisions, and vice

Obtain the prime number by using the screening method of the unique factorization theorem of ultraviolet A 10375. [number theory]
The basic content of the unique decomposition theory:
Any positive integer greater than 1 can represent the product of several prime numbers, and the representation method is unique. In other words, a number can be uniquely divided into the product of a prime factor. Therefore, this theorem is also called the unique decomposition theorem.
Example: 50 = (2 ^ 1) * (5 ^

Problem Description:
Five monkeys are divided into peaches. In the middle of the night, the first monkey get up first, it divides the peach into equal five piles, one more. So it ate one and took a bunch; the second monkey got up and looked, only four peaches. So the four piles together, divided into equal five piles, and one more. So, it also ate one, took a bunch of; Some of the other monkeys are divided like this. Q: There are at least as many peaches in this pile. Thinking Analysis:
Set the
remaining B (n,k)?
Take B (4,3) as an example to see if we can use B (3,?). Solve.
B (4,3) = 11, can be divided into two categories: one is x4 in pairs appear, a class is x4 into a single appearance.
Because k=3, so any 3 points can not shatter, namely: Α+β≤b (3,3).
And because for 2α, X4 is in pairs appear, so, x1,x2,x3 any two points
