i found a problem in heaviside(t-10) but when be in heaviside(10) it solve it !!

[ysm,xsm]=lsim(Asm,Gsm,H,zeros(k,r),5*u*heaviside(t-10),t,x0);
[yopt,xopt]=lsim(A-B*Kopt,G,H,zeros(k,r),5*u*heaviside(t-10),t,x0);

but I always get an error sound like

error using * Inner matrix dimensions must agree. I was trying to rewrite an expression like this:
