this is matlab verrrry simple program but i have verrrry simple problem 🙂 this is the error Error using mupadmex Error in MuPAD command: DOUBLE cannot convert the input expression into a double array.
If the input expression contains a symbolic variable, use the VPA function instead.Error in sym/double (line 936) Xstr = mupadmex('symobj::double', S.s, 0);Error in vib (line 10)nx=double( subs(x,'t',t));
and that is the program
vo=input('vo=');xo=input('xo=');wn=input('wn=');syms t;syms wn;a1=xo;a2=vo+(wn*xo);x=(a1+a2*t)*exp(-wn*t);t=0:0.5:1;nx=double( subs(x,'t',t));figure(1);plot(t,nx);
what can i do to solve this program
