Decreasing coordinate array in linint2_points_Wrap function

Hi all,
 
I want to interpolate ECMWF model data to fit stations locations using the function
 
fo = linint2_points_Wrap(xi, yi, fi, False, xo, yo, 0)
 
The variables of the ECMWF data, fi, are of the form fi(ti, lati, loni), so if I understand correctly,
 
fo = linint2_points_Wrap(loni, lati, fi, False, lon_station, lat_station,0)
 
should give me the interpolated values at stations locations lon_station and lat_station, at times ti (because the two rightmost dimensions (nyi x nxi) are the dimensions to be used in the interpolation)
The loni and lati should be increasing arrays, but the ECMWF latitudes are decreasing lati= [60, 59.75, 59.5, ... 50]. Can I then simply use -lati and apply linint2_points_Wrap?
 
fo = linint2_points_Wrap(loni, -lati, fi, False, lon_station, -lat_station, 0)
 
Hope I made myself clear, and you can give me advise,
Thanks
 
Lonneke
