Hi Everyone,

I have a matrix 25x68, each cell is either 1 or 0. I would like to reorder the matrix so that it is sorted according to the columns which has the most number of 1. Can someone help?

I will also like to reorder the label (x values) accordingly.

Thanks!

Just note that this is not what reshape means. Rearrange might be a better word.

在 MATLAB Online 中打开

>> M = randi([0,1],25,68);
>> [~,idx] = sort(sum(M,1));
>> cellplot(M(:,idx))

and use the index on the labels as well.
