Importing Packages Numpy


To save memory, when we import NumPy, only the basic libraries are imported. If we want a specialized subset of functions, we have to specifically import them. We do this with the from and import commands

Sage Cell

The * is part of a regular expression, and essentially tells the program to import everything in the specified package.


import numpy as np
from numpy.matlib import *
a = ones((2, 2))
print a


Useful Libraries

  • numpy.linalg: A set of linear algebra commands
  • numpy.matlib: A set of matrix and vector operations
  • numpy.polynomial: Commands for creating polynomial objects.
