A square matrix, a, is said to be diagonalizable if a is similar to a diagonal matrix. Numerical linear algebra adjoint of a matrix, 158160, 168169, 173 cramers rule, 161163, 169170, 173 cross product of two vectors in space, 336341, 350351, 355 cryptography, 102, 1114, 118119 geometry of linear transformations in the plane, 407410, 4414, 418 idempotent matrix, 98. Matrix algebras and displacement decompositions carmine di fiorey siam j. Introduction to linear algebra graduate school of mathematics. Essentially all the codes that are considered are linear codes, which means that the codewords form a vector space where the scalar multiplication is not by real. For example, d 300 0 0 60 0 000 0 000 10 is a diagonal matrix. Introduction to applied linear algebra stanford university. So we have a vector space of functions, and the methods of linear algebra are used to analyze the experiment. Our goal is to give the beginning student, with little or no prior exposure to linear algebra, a good grounding in the basic ideas, as well as an appreciation for how they are used in many applications, including data tting, machine learning and arti cial intelligence, to. It is used by the pure mathematician and by the mathematically trained scientists of all disciplines.
