matplotlib - Issue with inverting sparse matrix pylab -



matplotlib - Issue with inverting sparse matrix pylab -

i seek following

from scipy import * numpy import * import scipy s import numpy np import math import scipy.sparse l plot import graph3dsolution import numpy.linalg lin currentsol=s.sparse.linalg.inv(i-c)*a*lastsol

im missing out code issue this

traceback (most recent phone call last): file "explict1wave.py", line 62, in <module> currentsol=s.sparse.linalg.inv(i-c)*a*lastsol attributeerror: 'module' object has no attribute 'linalg' python 2.7.6 |anaconda 1.9.1 (x86_64)| (default, jan 10 2014, 11:23:15) [gcc 4.0.1 (apple inc. build 5493)] on darwin type "help", "copyright", "credits" or "license" more information. im>>> import scipy >>> scipy.__version__ '0.14.0' >>>

i documentation , seems these libraries existed since .12 . dont know issue is, im sure simple im not seeing.

>>> import scipy s >>> s.sparse traceback (most recent phone call last): file "<stdin>", line 1, in <module> attributeerror: 'module' object has no attribute 'sparse' >>> >>> scipy.sparse import linalg >>> linalg.inv <function inv @ 0x19b1758> >>>

general recommendations importing functions scipy .

on side note, best avoid star imports. these from scipy import *, from numpy import * not recommended , not needed here. same import scipy s.

matplotlib scipy

mediawiki - How do I insert tables inside infoboxes on Wikia pages? - i want insert tables in infoboxes. example, have proteinbox i've developed using infobox template (http://health-and-medicine.wikia.com/wiki/template:proteinbox), , fasta field big fit comfortably in proteinbox. hence collapsible table within box. this tried: {{infobox | row 1 = {| class = "mw-collapsible mw-collapsed wikitable" |- | <!-- table content --> |} }} your problem is, putting nested table within template. pipe characters ( | ) in table syntax collides pipe usage in templates. the commonly used hack around create template called template:! , containing pipe character, , utilize when need set tables, parser functions or other stuff using pipe characters, within templates. table (with every | replaced {{!}} ): {{{!}} {{!}}- {{!}} a1 {{!}} b1 {{!}}- {{!}} a2 {{!}} b2 {{!}}} ...the equivalent of {| |- | a1 | b1 |- | a2 | b2 |} furthermore, hav...
