Hi,
I want to run the following code in order to interpolate missing values of latitudes and longitudes between two dates.
% location of the known latitudes and longitudes
indKnownLATITUDE = ~isnan(arch.latitude);indKnownLONGITUDE = ~isnan(arch.longitude);% interpolate to obtain values of unknown values
arch.latitude(~indKnownLATITUDE) = interp1(arch.FECHATXT(indKnownLATITUDE),arch.latitude(indKnownLATITUDE),arch.FECHATXT(~indKnownLATITUDE)) ; arch.longitude(~indKnownLONGITUDE) = interp1(arch.FECHATXT(indKnownLONGITUDE),arch.longitude(indKnownLONGITUDE),arch.FECHATXT(~indKnownLONGITUDE)) ;
The error is:
Error using griddedInterpolant
The grid vectors must contain unique points.
F = griddedInterpolant(X,V,method);
I know I have to use the unique( ) function, so I've tried to introduce it in the code given above but it still gives me errors. Can you help me?
Thanks!
