Example run with -m

Here is an example illustrating the -m option. We examine the same two files as in the example without -m. The command line is:

$ max_diff_nc.sh -m 111/histrac.nc 113/histrac.nc

and here is the output:

standard output comment

 Found  25  variable(s) in the first file.

---------------------------------------------
Variable "zmasse":


Average value of log10(abs(data_old)):   3.

This is the additional information provided for each variable by the -m option. The average is computed over non-zero values of data_old, and the number of values used is the number of non-zero values.

 Relative difference for non-zero values:

Maximum difference: 3.3E-03
 Occurring at:
data_old(19 13 3 1) =  1522.2444
data_new(19 13 3 1) =  1527.2977

 Absolute difference:

Maximum difference:  7.
 Occurring at:
data_old(18 13 4 1) =  2297.566
data_new(18 13 4 1) =  2304.862

---------------------------------------------
Variable "d_tr_cv_RN":

Average value of log10(abs(data_old)):  -6.

 Relative difference for non-zero values:
