Comment (by wnbell):
Personally, I find it counterintuitive that an input parameter is modified
in-place since the solution is always returned as an output. I don't
believe it requires a significant change either, simply replace
{{{
x = x0
if x is None:
x = sb.zeros(n)
}}}
with
{{{
if x is None:
x = sb.zeros(n)
else:
x = array(x0)
}}}
Is there a standard SciPy convention when a function takes an initial
solution?
