1. function [posit_x] = Inter2Max(x,a,b)
2. r_x = size(x,1); % row of x
3. M = max([a-min(x),max(x)-b]);
4. posit_x = zeros(r_x,1); %zeros函数用法: zeros(3) zeros(3,1) ones(3)
5. % 初始化posit_x全为0 初始化的目的是节省处理时间
6. for i = 1: r_x
7. if x(i) < a
8. posit_x(i) = 1-(a-x(i))/M;
9. elseif x(i) > b
10. posit_x(i) = 1-(x(i)-b)/M;
11. else
12. posit_x(i) = 1;
13. end
14. end
15. end
