Jacket matrix

Jacket matrix

In mathematics, a Jacket matrix is a square matrix A= a_{ij} of order "n" whose entries are from a field (including real field, complex field, finite field ), if : AA^{mathrm{*= A^{mathrm{*A= n I_n where :A^{mathrm{* is the transpose of the matrix of inverse entries of "A" , i.e. :A^{mathrm{*=(a_{ji}^{-1}).Written in different form is:forall u,v in {1,2,dots,n}, u eq v:~sum_i {a_{u,i} over a_{v,i=0 .

Example

: J_4 = left [ egin{array}{rrrr} 1 & 1 & 1 & 1 \ 1 & -2 & 2 & -1 \ 1 & 2 & -2 & -1 \ 1 & -1 & -1 & 1 \ end{array} ight] , ~~~ J_4^{-1} = {1 over 4} left [ egin{array}{rrrr} 1 & 1 & 1 & 1 \ 1 & -{1 over 2} & {1 over 2} & -1 \ 1 & {1 over 2} & -{1 over 2} & -1 \ 1 & -1 & -1 & 1 \ end{array} ight] .

Jacket Matrices and other generalizations of Hadamard Matrices

Hadamard matrices are type of Jacket matrices. In the picture we present also other generalizations, and classes of matrices with similar properties.

Above are conditions, which 3 main classes of matrices must satisfy:

Orthogonal matrices::forall u,v in {1,2,dots,n}, u eq v:~sum_i {a_{u,i} . a_{v,i=0; ~~~ sum_i a_{u,i}^2 = const.

Matrices with zero complex inner product::forall u,v in {1,2,dots,n}, u eq v:~sum_i {a_{u,i} overline{a_{v,i}=0; ~~~ sum_i |a_{u,i}|^2 = const.

Jacket matrices::forall u,v in {1,2,dots,n}, u eq v:~sum_i {a_{u,i} over a_{v,i=0 .
