Can someone help in this program. I'm trying to find X and Y...for a MIMO system. While i'm multipying cellfunc multiplication causes order mismatch in this program. %% syms s num = {[1 0] , 1 ; 3 , [1 1]}; den = {[1 2 ] , [1 3] ; [1 6] , [5 2] }; G = tf(num,den) [A, B, C, D] = ssdata(G) [row, col] = size(A) %% delta = 3; %% Adash = inv(delta*eye(row)-A); Bdash = inv(delta*eye(row)-A)*B; Cdash = C*inv(delta*eye(row)-A); %% [r, c] = size(B); L = eye(c,r) %% ps=s-3; %% pole placement and finding K&F % multiplicity of desired pole location should not be greater than t rank(B), %hence different pole locations are chosen instead keeping all the poles % at one location, say -1 pole_place = ones(row,1); u = 1; for n = 1:row pole_place(n,1 )= -u; u = u+1; end K = place(A,B,pole_place); F = transpose(K); %% Htemp1= B*K; Htemp2 = ps*Htemp1; H = eye(row)-A-Htemp2 Mtemp1 = F*C; Mtemp2 = ps*Mtemp1; M = eye(row)-A-Mtemp2 %% finding X Xtemp1=ps*K; outX = cellfun(@(x) x*L,den,'un',0); outsys = cellfun(@(x) sym(x),outX,'un',0); Xtemp2=Xtemp1-outsys Xhf = inv(H)*F; Xtemp3 = Xtemp2*Xhf X = ps*Xtemp3 %% finding Y outY = cellfun(@(x) x*L,num,'un',0); Ytemp1 = C-outY Ytemp2 = Ytemp1*inv(H)*F Ytemp3 = ps*Ytemp2 Y = eye(c)-Ytemp3
