Thanks!
BTW would you consider changing the definition of spy(2) as shown below,
so that one could specify what 'to be a zero' means?
r.
def spy(self, Z, precision = None, marker='s', markersize=10, **kwargs):
if hasattr(Z, 'tocoo'):
c = Z.tocoo()
if precision is None:
x = c.row
y = c.col
z = c.data
else:
ii = where( abs( c.data ) > precision )[0]
x = c.row[ii]
y = c.col[ii]
z = c.data[ii]
else:
if precision is None:
x,y,z = matplotlib.mlab.get_xyz_where(Z, Z != 0)
else:
x,y,z = matplotlib.mlab.get_xyz_where(Z, abs( Z ) > precision)
return self.plot(x+0.5,y+0.5, linestyle='None',
marker=marker,markersize=markersize, **kwargs)
