I would like to sort a matrix according to a particular column. There is a sort
function, but it sorts all columns independently.
For example, if my matrix data
is:
1 3
5 7
-1 4
Then the desired output (sorting by the first column) would be:
-1 4
1 3
5 7
But the output of sort(data)
is:
-1 3
1 4
5 7
How can I sort this matrix by the first column?
