hi,

I'm trying a dynamics problem and trying to plot the displacement with

respect to time function. However I'm returned with an error message

"subscripts must be either integers 1 to (2^63)-1 or logicals

error: called from

utvst at line 7 column 3"

which I'm not able to figure out

thanks

t = linspace(0,0.01,500);

x0 = 0.01;

xdot0 = 0.1;

m = 40;

k = 3500;

omega = sqrt(k/m);

ut = sum((x0.*cos(omega.*t))+((xdot0/omega)(sin(omega.*t))));

plot(ut,t)
