• description: sddsdiff compares two SDDS files and reports differences in definitions and data.
• examples:
  sddsdiff file1 file2  
  sddsdiff data1.sdds data2.sdds -compareCommon=column -tolerance=1e-6  
      

• synopsis:
  sddsdiff <file1> <file2>  
    [-compareCommon[=column|parameter|array]]  
    [-columns=<col1>[,<col2>...]]  
    [-parameters=<par1>[,<par2>...]]  
    [-arrays=<array1>[,<array2>...]]  
    [-tolerance=<value>] [-precision=<integer>]  
    [-format=float=<string>|double=<string>|longdouble=<string>|string=<string>]  
    [-exact] [-absolute] [-rowlabel=<column>[,nocomparison]] [-ignoreUnits]  
      

• switches:
  • -compareCommon[=column|parameter|array] — Compare only items present in both files.
  • -columns=<col1>[,<col2>...] — Limit comparison to the listed columns.
  • -tolerance=<value> — Set numerical comparison tolerance.
  • -precision=<integer> — Set precision for floating-point comparisons.
  • -exact — Require exact equality of values.
  • -absolute — Compare absolute values, ignoring signs.
  • -rowlabel=<column>[,nocomparison] — Use a column to label rows.
  • -ignoreUnits — Ignore units during comparison.
• files: file1 and file2 are SDDS files to be compared.
