The present article introduces the concept of Global Baseline Matrix associated with M(r,c) subsets of Complex Matrix spaces of order ‘m’ by ‘n’, where m≠n. It then presents a mathematical scheme to define subspaces of the corresponding Matrix space using elements of M(r,c) subset that are involved in computation of the Global Baseline matrix. The article next introduces the concept of “Local Baseline Matrix”, i.e. the Baseline matrix associated with an element of the M(r, c) subset and finally develops the concept of Fundamental subset associated with an element of M(r, c) subset

Keywords : M(r,c) subsets of Complex Matrix spaces, Global Baseline Matrix of M(r,c) subsets, Baseline Matrix of elements of M(r,c) subsets, Spacer Matrices associated with Complex Matrix spaces, Discrete dynamical systems, Markov Matrix, Hadamard Product of matrices
