How to pass an array into the initial condition function while using pdepe

I have a PDE which is solved using pdepe. However after the solution (1xn array) is achieved, i perform some other calculation and then i want to feed the end result back into the PDE (in the next iteration in a for loop) as initial condition. How can this be achieved.
Additinally how can additional paramters be passed into the pde function?

Define
icfun = @(x)interp1(X,U,x)
where X is the mesh vector and U is the vector of initial values corresponding to X you want to feed back into the solver for the next iteration.

x is just a formal parameter - MATLAB does not expect it to have a value when you define the function "icfun". It will not conflict with variables explicitly set in your code. Simply make sure that X and U in your definition of "icfun" are your solution mesh vector and your solution from the first call to "pdepe". The name "x" can be replaced by any other name in the definition of "icfun".
Maybe before proceeding you should pass the free MATLAB online tutorial:
