[JESUS DAVID ARIZA ROYETH]

what is the problem with the third dataset?

[Asliddin Komilov]

it says:

Error using griddedInterpolant

The grid vectors must contain unique points.

Error in interp1 (line 161)

F = griddedInterpolant(X,V,method);

Have you checked if all the values are unique? You can make them unique by adding eps to one of the duplicates.

I checked the data, it all runs fine.. no duplicate data

The below entry numbers ignore the header line (so they refer to array indices)

Entry #102 occurs again at #111

Entry #105 occurs again at #108

Entry #113 occurs again at #128

Entry #101 occurs again at #117 and #119
