Hello, When I write matrix(2,2,1) or matrix(QQ,3,3,1) I do not get the identitiy matrix.
The only way the matrix function works is when I type matrix() and it gives me an empty matrix. Why is this so? Have I not installed some package correctly? Below is the error message that I get. sage: matrix(2) --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) /home/eren/sage/<ipython console> in <module>() /home/eren/sage/local/lib/python2.7/site-packages/sage/matrix/constructor.pyc in matrix(*args, **kwds) 497 # check to see if the number of rows is specified 498 try: --> 499 import numpy 500 if isinstance(args[0], numpy.ndarray): 501 raise TypeError /home/eren/sage/local/lib/python2.7/site-packages/numpy/__init__.py in <module>() 134 return loader(*packages, **options) 135 --> 136 import add_newdocs 137 __all__ = ['add_newdocs'] 138 /home/eren/sage/local/lib/python2.7/site-packages/numpy/add_newdocs.py in <module>() 7 # core/fromnumeric.py, core/defmatrix.py up-to-date. 8 ----> 9 from numpy.lib import add_newdoc 10 11 ############################################################################### /home/eren/sage/local/lib/python2.7/site-packages/numpy/lib/__init__.py in <module>() 11 12 import scimath as emath ---> 13 from polynomial import * 14 #import convertcode 15 from utils import * /home/eren/sage/local/lib/python2.7/site-packages/numpy/lib/polynomial.py in <module>() 9 import re 10 import warnings ---> 11 import numpy.core.numeric as NX 12 13 from numpy.core import isscalar, abs, finfo, atleast_1d, hstack AttributeError: 'module' object has no attribute 'core' Thank you again -- You received this message because you are subscribed to the Google Groups "sage-support" group.
