hi Email Address:::: rafe.torabi@gmail.com

help me ; help me plz I write code for Inference but it have error below:::

??? Error using ==> subsindex Function 'subsindex' is not defined for values of class 'cell'.

Error in ==> discrete_CPD.convert_to_table at 14 T = CPT(index{:});

Error in ==> discrete_CPD.convert_to_pot at 20

T = convert_to_table(CPD, domain, evidence);

Error in ==> jtree_inf_engine.enter_evidence at 57

pot{n} = convert_to_pot(bnet.CPD{e}, pot_type, fam(:), evidence);

Error in ==> Rafe_inference at 116 engine,loglik? = enter_evidence(engine,evidence);

my code is :::::

clear all

N=6;

dag=zeros(N,N);

AS=1;AM=2;CC=3;SC=4;VT=5;DA=6;
