Derivative of product of matrices
WebDec 22, 2008 · Matrix metalloproteinases (MMPs) are a family of more than twenty five secreted and membrane-bound zinc-endopeptidases which can degrade extracellular matrix (ECM) components. They also play important roles in a variety of biological and pathological processes. Matrix metalloproteinase inhibitors (MMPIs) have been identified … Web1 Properties of the Matrix Exponential Let A be a real or complex n×n matrix. The exponential of A is defined via its Taylor series, eA = I + X∞ n=1 An n!, (1) where I is the n×n identity matrix. The radius of convergence of the above series is infinite. Consequently, eq. (1) converges for all matrices A. In these notes, we discuss a ...
