matlab遗传算法中的代码含义

Question

    POP.NEWchrom1(i,:) = [POP.chrom1(i,1:cpoint(1)),POP.chrom1(i+1,cpoint(1)+1:chromlength(1))]; 
    POP.NEWchrom1(i+1,:) = [POP.chrom1(i+1,1:cpoint(1)),POP.chrom1(i,cpoint(1)+1:chromlength(1))];
    POP.NEWchrom2(i,:) = [POP.chrom2(i,1:cpoint(2)),POP.chrom2(i+1,cpoint(2)+1:chromlength(2))];
    POP.NEWchrom2(i+1,:) = [POP.chrom2(i+1,1:cpoint(2)),POP.chrom2(i,cpoint(2)+1:chromlength(2))]; 

遗传算法中，请问这几行交叉互换代码是什么意思？
