How to sort vector alternatively
显示 更早的评论
I have a vector a=[1 3;3 4;3 6;4 8]; I want to alternatively sort matrix ‘a’ row wise (second column), i.e Highest element in second column should be row 1; second to highest element in second column shall be last row; third to highest element in second column shall be second row; and so on So, output shall be [4 8;3 4;1 3;3 6] Thanks
This command is working for sorting in order only b=sortrows(a,-2);

>> a = [1,3; 3,4; 3,6; 4,8]
a =
1 3
3 4
3 6
4 8
>> tmp = sortrows(a,2);
>> [tmp(1:2:end,:);flipud(tmp(2:2:end,:))]
ans =
1 3
3 6
4 8
3 4
@Vishal Sharma: did you know that the less effort you put into solving your own homework problems then the less you will learn. Also note that copying someone else's works and presenting it as your own is called plagiarism, and in many countries is considered a serious criminal offense.
