Hi everbody.
Sometimes i give an error when making interpolation process for ex. "The values of X should be distinct error".
I have an exam this tuesday which will be done by matlab. And i am afraid of interpolation errors.
What are the alternative methods for interpolation or solutions of errors like "The values of X should be distinct" etc.?
Thanks a lot.

The available techniques depend a great deal upon whether the Y corresponding to the duplicate X are the same or different.
If the Y values are the same then the major technique is to unique() the X values and take the corresponding Y values. One way of doing that is to use
XY = [X(:), Y(:)];
uXY = unique(XY,'rows');
uX = uXY(:,1);
uY = uXY(:,2);
interp1(uX, uY, locations_to_interpolate_at)
But typically one would instead construct the X values to be unique.
What are some circumstances under which you have had difficulty with duplicate X values?
