Find the roots of a function.
Description:
Return the roots of the (non-linear) equations
defined by
func(x)=0 given a starting estimate.
Inputs:
func -- A Python function or method which takes at
least one
(possibly vector) argument.
x0 -- The starting estimate for the roots of
func(x)=0.
args -- Any extra arguments to func are placed in
this tuple.
fprime -- A function or method to compute the
Jacobian of func with
derivatives across the rows. If this is
None, the
Jacobian will be estimated.
full_output -- non-zero to return the optional
outputs.
col_deriv -- non-zero to specify that the Jacobian
function
computes derivatives down the columns
(faster, because
there is no transpose operation).
warning -- True to print a warning message when the
call is
unsuccessful; False to suppress the
warning message.
Outputs: (x, {infodict, ier, mesg})
x -- the solution (or the result of the last
iteration for an
unsuccessful call.
