plish tasks such as projecting a three-dimensional object onto a two-dimensional screen, corresponding to a theoretical camera observation.[61] Matrices over a polynomial ring are important in the study of control theory.Chemistry makes use of matrices in various ways, particularly since the use of quantum theory to discuss molecular bonding and spectroscopy. Examples are the overlap matrix and the Fock matrix used in solving the Roothaan equations to obtain the molecular orbitals of the Hartree–Fock method.ප්‍රස්තාරික සිද්ධාන්තය[සංස්කරණය]An undirected graph with adjacency matrix [210101010].{\displaystyle {\begin{bmatrix}2&1&0\\1&0&1\\0&1&0\end{bmatrix}}.}The adjacency matrix of a finite graph is a basic notion of graph theory.[62] It saves which vertices of the graph are connected by an edge. Matrices containing just two different values (0 and 1 meaning for example "yes" and "no") are called logical matrices. The distance (or co
