the program is well written, but i believe the state space representation is wrong.
Though the implemented part is as mentioned in the refernce paper still , I argue about the 'R' in arma_ConvertToSS

Taking the MA parameters directly is not the proper representation.
instead R=[ c1-a1;c2- a2-( c1-a1);.....];
