I have this system
A = [ 1 1 -1 ; 0 -1 1 ; 0 1 -1 ];
B = [ 1 0 ; 0 1 ; 0 0 ];
C = [ 1 0 0 ];
D = [ 0 ] ;
sys = ss( A , B , C , D )
Now i have to put two signals in input with lsim the two signals are u1( t ) = 2*square( t ) and u2( t ) = 0 i have written something like this
figure( 2 ) ;
t = 0:0.01:10 ;
u = [ 2*square( t ) ];
u2 = zeros( size( t ) ) ;
sys2 = tf( sys ) ;
lsim( sys2 , u , t , x0 );
but i continue to have this error
Error using DynamicSystem/lsim (line 97) When simulating the response to a specific input signal, the input data U must be a matrix with as many rows as samples in the time vector T, and as many columns as input channels.
I have tried many ways but i don't know what to do it there isn't nothing on the internet on multi input with lsim please help !
I thank in advance any of you
