[Octave-bug-tracker] [bug #54622] test importdata fails in dev octave with windows

[Rik]

Follow-up Comment #21, bug #54622 (project octave):

I think we are narrowing this down to an issue associated only with importdata
that is probably in the second half of importdata_ascii.

For speed, importdata first does a dlmread of the file.  After that, it goes
back over the file to find values that did not convert.  In this case, NA,
converts to NA and needs to be left alone.  Inf/-Inf are exceptional values,
but not NA values. 


  ## Now, let the efficient built-in routine do the bulk of the work.
  if (delimiter == " ")
    output.data = dlmread (fname, "", header_rows, header_cols,
                           "emptyvalue", NA);
  else
    output.data = dlmread (fname, delimiter, header_rows, header_cols,
                           "emptyvalue", NA);
  endif

  ## Go back and correct any individual values that did not convert.
  na_idx = isna (output.data);
