Error: Sample points must be unique and sorted in ascending order.

I have the following data. But when I am trying to interpolate it is giving

Error using matlab.internal.math.interp1

Sample points must be unique and sorted in ascending order.

Error in interp1 (line 154)

VqLite = matlab.internal.math.interp1(X,V,method,method,Xqcol)

Kindly help me out.

Thanks in advance.

You can use unique() to get rid of duplicate sample points. It will also sort them.
