Is there any existing POMDP library/function in MATLAB?

I am looking for an existing Partially Observable MDP (POMDP) library/function that implements a simple POMDP problem using, let's say, Enumeration algorithm. Basically, I have developed my own algorithm for the pruning stage of solving POMDP, and thus need an existing library where I can replace the pruning part with my own pruning algorithm. I have tried writing my own code to do that for a POMDP problem (Tiger-problem) but somehow does not match the results that I found using existing POMDP structures in Julia and R. I have attached the codes I have written (I haven't attached my pruning algorithm though for obvious reasons).

Any help will be highly appreciated. Thanks in advance!

FYI: My pruning algorithm works perfectly because I have verified the algorithm using random alpha vectors.

My Matlab based toolbox MDPSolve has several POMDP solvers. pomdp solves using discretization of the belief states, pomdpsolve uses an alpha vector approach.
