b2f.m

人工免疫算法基于遗传MATLAB代码很有用哦

function [fval] = b2f(bval,bounds,bits)
%
% Return the float number corresponing to the binary representation of bval.
%
% fval   - the float representation of the number
% bval   - the binary representation of the number
% bounds - the bounds on the variables
% bits   - the number of bits to represent each variable
