function ReverseB = AiMReverseCoeffMatrix(B)
% AiMReverseCoeffMatrix: Reverses the temporal ordering of an AIM-ordered coefficient matrix (usually BMatrix)
%
% USAGE:
%
%       ReverseB = AiMReverseCoeffMatrix(B)
%
% REQUIRED INPUTS:  B (nxnq) matrix with coefficients ordered as B(q), B(q-1), ..., B(1)
%
% REQUIRED OUTPUTS: rcf (nxnq) matrix with coefficients ordered as B(1), ..., B(q-1), B(q)
%
%
% ACKNOWLEDGEMENTS: This function is based on reverse.m that comes with AiM util
