In the previous articles, it was described how the transformation between consecutive links of a manipulator can be described using local coordinate frames and the 4 Denavit-Hartenberg parameters. The parameters describe 2 translational and 2 rotational degrees of freedom, which correspond to 4 transformations, that are applied successively to transform coordinate frame K_n with respect to frame K_{n-1} like shown below.

Based on this, the A-matrices are used to describe the precise transformation of a link with respect to the previous link resulting of the 4 successive transformations described by the Denavit-Hartenberg parameters.
