finding the 10 lowest values
显示 更早的评论
I have a matrix with a lot of data, and i want to find the 10 lowest values of a specific collum.
Does anybody know how to do that?
i was thinking about using the function min() but it does not allow me to select a specific collum, or finding more than the one value which is the lowest.

- Let's say you have a matrix of 10x10:
x=rand (10,10);
- Sort it by the columns in ascending order:
y=sort (x,1, 'ascend')
*Now take the 5 first rows - these are the lowest values in every column:
z=y(1:5, :)

First 10 values of "sorted_x" is what you want.
A = rand(100,10);
columnToSort = 7;
[sorted_x, index] = sort(A(:,columnToSort),'ascend');
