Hi there<
Solving PDE using Matlab
## type 1
I have a pde of this type:
 1/2/P*(1-r^2)del_c/del_x=del^2_c/del_r^2+1/r*del_c/del_r
Where P is a constant, r and x is radial and axial direction respectively (nondimensional), c is a non dimension function
The two boundary conditions are:
c=1, at x=0, for all positive r
c=0, at r=1 for all positive x
Finally I need:
for all del_c/del_r, at r=1
## type 2
The original equation is now:
 1/2/P*(1-r^2)del_c/del_x=del^2_c/del_r^2+1/r*del_c/del_r+del^2_c/del_x^2
Everything else remains the same.

Please send the solution to docnurulhasan@gmail.com  if you have one.
