with(LinearAlgebra):
    
A:= Matrix([[1,0,0],[cos(4*Pi/T),1,0],[sin(6*Pi/T),cos(6*Pi/T),1]]);
B:= Matrix([[0,sin(2*Pi/T),cos(2*Pi/T)],[0,0,sin(4*Pi/T)],[0,0,0]]);
c:= Matrix([[1,x[22],x[23]],[0,1,x[32]],[0,0,1]]);
h:= Matrix([[0,0,0],[y[21],0,0],[x[31],x[32],0]]);
eq:= c.c^%T+h.h^(%T)-(A . A^%T + B . B^%T);
fff:=seq(seq(eq[i,j],j=1..3),i=1..3);
Ss:= solve({fff});
