Thanks in advance, No, you need to type some more. :-) You need to define function def f(x): return x + 1 and call root solver, either from a library or function imported from module. For simple cases, I use RPN calculator recently added to Bash shell, like rpn 'f(x)= 1 +' 0 1 secant = rpn 'f(x)= 1 +' 'fd(x)= 1' 0 newton = -- William Park [EMAIL PROTECTED], Toronto, Canada ThinFlash: Linux thin-client on USB key (flash) drive http://home.eol.ca/~parkw/thinflash.html BashDiff: Super Bash shell http://freshmeat.net/projects/bashdiff/ -- http://mail.python.org/mailman/listinfo/python-list
Re: formal math ?
Thanks you two. I was just thinking if it was possible. If I really want to do this, maybe the best way is to do an interface to python of an open source project I have just discovered : maxima. So long, -- http://mail.python.org/mailman/listinfo/python-list
