This function find the gains of Full-Order Darouach Observer of 1995 paper [1]
[N,K,L1,L2,G,test]=darobsv95(E,A,B,C,poles)
Continuos matrices of descriptor system. E singular
Desired poles of the observer
Gains matrices of Darouach Observer
test if the observer condition is true
Given a Descriptor system in the form dxEdt=Ax+Bu y =Cx+Du if the conditions in [1] are satisfied, then exist a full order observer dzdt=Nz +L1y + L2y +Gu xhat=z +by +Kdy where b and d are founded with abccoeff function
