zeta = g * q;
j= 1-power(zeta,2);
wd = w*power(j,1/2);
r=w./wd;
k = zeta*r;
l=k*sin(wd*t);
m=cos(wdt) + l;
n= - zeta*w*t;
p = 1 - exp(n)*(m);
plot (p)

You are using the / operator in several places. In MATLAB, A/B is more or less the same as A * pinv(B) . 1/w where w is 60 x 1, gives you a 1 x 60 result. Likewise, h = xt/ i where i is 60 x 1, gives you a 1 x 60 result. You then end up working with this mix of 60 x 1 and 1 x 60 and you end up with trying to combine arrays in the wrong way.
>> 1/[2;4;3]
ans =
0 0.25 0
Notice the output is a row vector for a column vector divisor.
If you would need the answer [0.5; 0.25; 0.3333] (column vector, individual divisions) instead for this calculation, then you need to use the ./ operator
