I have this code to flipud every other line along x-axis. The code works (only) when the increment on x-axis is an integer number(1,2,3...or 4 etc) as in data (a) attached, result shown in the first figure for 2 increment . but when the increment on x-axis is a fraction(1.123 or 1.234, ...or etc) as in data (b) attached, it only work for the first line as shown in the second Figure for 1.123 increment.
I think the reason is that I need to add a tolerance to the result of desired_line so Matlab can find it and add it to the desired_line_matrix. because of precision issue.
_ But i don't know how to add the tolerance of search !!!!_
Thank you so much
