Class DAA, "Derivative-Augmented Array", is a general-purpose automatic differentiation engine implemented in MATLAB. DAA supports differentiation of standard array operations and numeric functions with respect to any number of parameters, to any derivative order. The class is implemented to operate efficiently with large numeric arrays and with sparse functional dependencies (i.e., many zero or constant derivatives).
(DAA is superseded by class mpoly: https://www.mathworks.com/matlabcentral/fileexchange/182185-class-mpoly-multivariate-polynomial.)
