Re: [Numpy-discussion] matrix file format

Any format you like, but you have to supply the I/O code yourself.
Which however is really simple. For example, the following
function from ScientificPython:

  from Scientific.IO.TextFile import TextFile
  import string, Numeric

  def readArray(filename):
      "Return an array containing the data from file |filename|."
      data = []
      for line in TextFile(filename):
	  if line[0] != '#':
	      data.append(map(eval, string.split(line)))
      a = Numeric.array(data)
      if a.shape[0] == 1 or a.shape[1] == 1:
	  a = Numeric.ravel(a)
      return a
