I have 3X6 matrix:
M=[15 18 14 19 17 14;
30 3 8 14 1 5;
7 16 13 11 20 2] ;
It is required to sort them using only one of the smallest value in the column (i.e. the column which contain the smallest value should be first column in the matrix without change the order of original column). The sorted output should be displayed as:
M=[17 14 18 19 15 14;
1 5 3 4 30 8;
20 2 16 11 7 13];
Since the value 1 is the smallest value in column 5 at the original matrix, it comes in the first column for sorted output matrix.

@Keyre: It matters for the kind of answering, if this is a homework or not. Please be so kind and clarify this.

My guess is that it is unlikely to be a homework assignment. If it is, I hope my solution won't get credit. It only takes two lines of code using built-in MATLAB functions.

I think this is the way to do it. Your expected output has typo in it.
M=[15 18 14 19 17 14;
30 3 8 14 1 5;
7 16 13 11 20 2] ;
MinM=min(M);
[~,Index]=sort(MinM);
NewM=M(:,Index)
NewM =
17 14 18 15 14 19
1 5 3 30 8 14
20 2 16 7 13 11
