[Phi,List] = vma(M,P,...)
M [ model ] - Model object for which the VMA representation will be computed.
P [ numeric ] - Order up to which the VMA will be evaluated.
Phi [ namedmat | numeric ] - VMA matrices.
List [ cell ] - List of measurement and transition variables in the rows of the Phi matrix, and list of shocks in the columns of the Phi matrix.
'matrixFmt=' [ 'namedmat' | 'plain' ] - Return matrix Phi as either a namedmat object (i.e. matrix with named rows and columns) or a plain numeric array.
'select=' [ @all | char | cellstr ] - Return VMA for selected variables only; @all means all variables.
