产生任意均值与方差的一个正态分布随机数-have arbitrary and mean variance normal distribution of a Random Number

设计出一个算法，贪吃蛇小游戏怎么做出来的，利用C++语言编写，代码简单，很容易看懂，function [p,ff] = oct3bank(noi);  pi = 3.14159265358979;  Fs = 500000;    %1/(t(2)-t(1));     % Sampling Frequency N = 3;      % Order of analysis filters.  %f=[1.00 1.25 1.60 2.00 2.50 3.15 4.00 5.00 6.300 8.00] ff=[20 25 31.5 40 50 63 80 100 125 160 200 250 315 400 500 630 800 1000 1250 1600 2000 2500 3150 4000 5000 6300 8000 10000 12500 16000] %ff = ((2^(1/3)).^[0:19]);  % Exact center freq.   p = zeros(1,30); % Design filters and compute RMS powers in 1/3-oct. bands
