Ndsparse Description

n-dimensional sparse arrays for Python Ndsparse is a Python module that provides one class for creation of ndsparse objects which behave similar to numpy ndarray objects, including slicing and basic arithmatic operations.Sparse array objects are stored using a flat index and a data value, so only take up space for elements explicitly added which makes them efficient for storing large arrays where only a few positions are occupied.Slicing returns an ndsparse object which can be converted to a dense numpy.ndarray by calling it's dense() method.Single element access returns the stored value if available or a default value otherwise. Requirements: · Python What's New in This Release: · This release adds a helper function sparse() which converts a Numpy ndarray object to a ndsparse object. · It also fixes some minor bugs.
