Note that each line in the text file must have the same number of values.
Syntax: numpy.loadtxt (fname, dtype = ’float’, comments = ’#’, delimiter = None, converters = None, skiprows = 0, usecols = None, unpack = False, ndmin = 0)
Parameters:
fname: File, filename, or generator to read. If the filename extension is .gz or .bz2, the file is first decompressed. Note that generators should return byte strings for Python 3k.
dtype: Data-type of the resulting array; default: float. If this is a structured data-type, the resulting array will be 1-dimensional, and each row will be interpreted as an element of the array.
delimiter: The string used to separate values ... By default, this is any whitespace.
converters: A dictionary mapping column number to a function that will convert that column to a float. Eg, if column 0 is a date string: converters = {0: datestr2num}. Default: None.
skiprows: Skip the first skiprows lines; default: 0.Returns: ndarray
