how can I solve this partial derivatives

dc/dz = (a/x * dc/dx +a*d^2c/dx^2) /(1-x^2/L) where a,L are constant.

Use pdepe.

but pdepe is for time dependent function and space varial is only x. but in this case x,y.

[Shangeetha Mahendran]

x,y,c are variables

[Torsten]

In your equation, there is no y.

If you interpret z as t and x as x, pdepe is the correct tool to use.

Thank you.
