Hi,
I am addressing this to the whole list because I don't know who is
maintaining the manual.
I noticed that the package "newton1" is not in the 5.9.3 manual.
Doing ? newton brings up
%i2) ? newton;
0: (contrib.info)Definitions for mnewton.
1: mnewton :Definitions for mnewton.
2: NEWTONEPSILON :Definitions for mnewton.
3: NEWTONMAXITER :Definitions for mnewton.
Enter space-separated numbers, `all' or `none':
In v. 5.9.2, there was:
(%i1) ? newton;
Info from file /usr/local/info/maxima.info:
-- Function: newton (<expr>, <x>, <x_0>, <eps>)
Interpolation by Newton's method. `load ("newton1")' loads this
function.
`newton' can handle some expressions that `interpolate' refuses
to
handle, since `interpolate' requires that everything evaluate to
a
floating point number. Thus `newton (x^2 - a^2, x, a/2,
a^2/100)'
complains that it can't tell if `6.098490481853958E-4 a^2 <
a^2/100'. After `assume (a>0)', the same function call succeeds,
yielding a symbolic result, `1.00030487804878 a'.
On the other hand, `interpolate (x^2 - a^2, x, a/2, 2*a)'
complains
that `0.5 a' is not a floating point number.
An adaptive integrator which uses the Newton-Cotes 8 panel
quadrature rule is available. See `qq'.
(%o1) false
I noticed that the package "newton1" is still there.
Is it intended that "mnewton" simply replace "newton1" ?
