how can 4*4 matrix is created?

how can we get 4*4 matrix from 4 row matrix?

how can particular column elements selected from 4*4 matrix?

How inverse matrix calculated by using LU decomposition for 4*4 matrix?

Can you go into any more details? have you got code you've started already?

All of this is possible with VHDL..

as a part of my project on Hill Cipher algorithm .

Actually i want take 4-bit binary vector as input. by taking four such vector create a 4*4 matrix from it,then select elements from column and multiply with another 4*4 binary matrix.

thanks a lot!!

pivoting of matrix in vhdl

use an array and write a function. E.g.

type t_matrix is array (0 to 3) of bit_vector(0 to 3);
signal s_matrix : t_matrix := (others => (others => '0'));

function pivot_matrix(input_matrix : t_matrix) return t_matrix is
    variable output_matrix : t_matrix;
begin
    
    return output_matrix;
end function;
