* summary: [with patch, with positive review after some typos are fixed]
update desolver interface => [with patch, with
positive review] update desolver interface
Comment:
Typos fixed.
I imagine we'll be using maxima for differential equations for a while
yet, but this interface will almost certainly be affected by the move to
PyNaC all the same.
wdj: there is no need to use a lambda function, you can directly write
{{{
sage: t = var('t')
sage: x = function('x', t)
sage: de = diff(x,t) + x - 1
sage: desolve(de,[x,t])
e^(-t)*(e^t + c)
sage: f = desolve(diff(x,t) + x - 1, x, ics=[10,2]); f
e^(-t)*(e^t + e^10)
sage: plot(f)
}}}
