描述混沌现象的判断及其使用MATLAB对该过程的仿真的程序源码

function Y = selb(M1, M2, mp)
%Y = selb(M1, M2, mp) coefficient selection for base image
%
%    M1  - coefficients A
%    M2  - coefficients B
%    mp  - switch for selection type
%          mp == 1: select A
%          mp == 2: select B
%          mp == 3: average A and B
% 
%    Y   - combined coefficients
