[ncl-talk] Report of error in web example.

Hi Joowan,

you’re right but you can use the newer str_split_csv function to get all elements into a 2D array directly:

begin
  filename = "example1.csv"

  data = asciiread(filename,-1,"string”)
  print("______________")

;-- use str_split_csv to get 2d array
  ncols = dimsizes(str_split(data(0),","))

  values_2d = toint(str_split_csv(data, ",", 0))
  print(values_2d)
  print("______________")

  write_matrix(values_2d,ncols+"I5",False)

end

Terminal output:
 > ncl csv_1.ncl
