Jacket matrices which are defined to be mtimesm matrices J = [jik] over a field F with the property JJdagger = mIm, J is the transpose matrix of elements inverse of J. i.e., Jdagger = [jik -1]T, was introduced by Lee in 1984 and are used for digital signal processing and coding theory. This paper presents some square matrices A2n which can be eigenvalue decomposed by Jacket matrices. Specially, A2 and its extension A3 can be used for modifying the properties of hyperbola and hyperboloid, respectively. The ideas that we will develop here have applications in computer graphics and used in many important numerical algorithms.
