[sage-support] Re: Issues with bessel function.
Not sure how to go about doing that. Anyways I tried running the code
for the previous bessel functions I successfully plotted, and the
error shows up as well. Looks like there is an issue with the sage
code not sure where, and what I can do about it. Also I keep the
previous version on hand in cause I have an issue however the same
error pops up.

What are 'y' and 't'? When did it crash -- while you were typing it in,
when Psi was called, or when the returned function was called?
I tried guessing at some inputs and haven't seen the error. If you could
come up with a test case it would help!

I think what Michael means is that if we saw an entire (failing)
session it would help debug things more easily. You can paste it
here, or someplace like http://pastebin.com/ if it's pretty long.

So I take it I am suppose to use debug which should the generate the

[sage-support] Re: Issues with bessel function.
If I did this correctly. This is the error I get from the debugger.
error:
-
*** SyntaxError: can't assign to function call (stdin, line 1)
the code I used was:
-
r,p,z,g,k,ro,gro = var('r,p,z,g,k,ro,gro')
g = 1; k = 1; ro = 1; gro = 1
Psi(r,z) = lambda r,z: ((r*bessel_J(1, g*r))/
(ro*bessel_J(1,gro)))*(cos(k*z))
The psi function is the line of code that has the issue.
The steps I took to use the debugger was:
sage:pdb
Automatic pdb calling has been turned ON
sage: r,p,z,g,k,ro,gro = var('r,p,z,g,k,ro,gro')
sage: g = 1; k = 1; ro = 1; gro = 1
sage: Psi(r,z) = lambda r,z: ((r*bessel_J(1, g*r))/
(ro*bessel_J(1,gro)))*(cos(k*z))

Do not use 'Psi(r,z) = ...', just use 'Psi = ...'. Such as:
r,p,z,g,k,ro,gro = var('r,p,z,g,k,ro,gro')
g = 1; k = 1; ro = 1; gro = 1
Psi = lambda r,z: ((r*bessel_J(1, g*r))/ (ro*bessel_J(1,gro)))*(cos(k*z))
