nsidc / nsidc0756-scripts Goto Github PK

I attempted to use the xy2ll for both MATLAB and python. I used the x and y data from the BedMachine .nc file. In both instances of running the script I ran into the errors
For Python:
ufunc 'square' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

For MATLAB:
Check for incorrect argument data type or missing argument in call to function 'sqrt'.
rho=sqrt(x.^2+y.^2);

In Python I was able to fix the issue by importing the x and y values as a dtype='int64' numpy array. Some stackoverflow searchers made it seem like the error was an integer overflow issue. However the output longitude values only varied from -45 to 135 and not -180 to 180.

Any help would be much appreciated.
