beta rand

Copy CodeThe code is as follows: function Yzm ($name, $width, $height) {Header ("Content-type:image/png");Srand (Double) microtime () *1000000);//sow a seed that generates random numbers to facilitate the use of random number generation

For example, a random value rand (range: 1-100) is generated ). The probability of a small value in rand is very high, but the probability of a large value is very low. I hope you can give a specific formula. The random value can be replaced by rand.

All the random number functions of MATLAB(i) MATLAB internal functionsA. basic random numberThere are two basic functions for generating random numbers in MATLAB.1 . rand ()Generates a random variable that is evenly distributed over the (0,1)

Introduction: Basic PSO algorithm implemented in C Language C language implementation of the standard PSO algorithm 1. first look at the language description of the PSO to summarize the core idea of particle swarm optimization (PSO) in one sentence:

Summary:In this paper, the FCM algorithm is mainly limited to deal with the shortage of star cluster data, and the kernel method is introduced to optimize the algorithm. as with many clustering algorithms, FCM chooses Euclidean distance as the

Recently look at the pattern recognition related books, access to some common machine learning algorithms, although the book for the theory of the algorithm is very clear, but rarely give the specific function definition of the algorithm, so I would

Using MATLAB, the implementation process of QR was written based on householder change 1, Householder change algorithm function [H, V, beta] = Householder (x) % x:inout param. x is a vector which the size is n*1 % v and beta:is PA Ram which
