Matrix row swapping with respect to column

How to swap between two rows of matrix with respect to column? For example: matrix A is: 1 3 4; 2 4 5 and Y want to be 1 4 5;2 3 4 , only 2nd and 3rd coulm row values have to be interchanged.? I want a generalised equation so that when I input the column no,numbers between the said column to end in a particular row has to be swapped with the next row.

"only 2nd and 3rd coulm row valuese have to be interchanged.?"

Y=[1 3 4; 2 4 5]
Z=Y;
Y(:,2)=Y(:,3);
Y(:,3)=Z(:,2);
Y

Result:

Y =
     1     3     4
     2     4     5
Y =
     1     4     3
     2     5     4

I have no idea why Kalyan is making an easy task really harder but here is what you want:

Y = A;
Y(:,[2,3]) = flip(Y(:,[2,3]))
