What is it?

This is a program which compares two NetCDF files. Only NetCDF variables with type NC_FLOAT or NC_DOUBLE are compared. The program either compares variables with the same NetCDF ID (varid) or variables with the same name. Compared variables are assumed to have the same type and the program checks that they have the same shape. For each such couple of variables, the program computes the maximum of the absolute value of the difference, and the maximum of the absolute value of the relative difference. The program also tells you at what location (the subscript list of the array) the maximum difference is reached.
