t = linspace(t1,10,200);
x(t) = ((F0*exp((-zeta*omega*t.)))/(k*sqrt(1-zeta^2)))*((exp(zeta*omega*t1)*cos(omega*(t.-t1))-phi)-cos(omega*t.-phi));
First I got this error
Error using *
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix
matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'.
Then I added '.*' after every 't' and now I get the following error. Where am I getting this wrong?
Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check
for mismatched delimiters.

You need dots before the * and before the / , not after the t.

You will need to post your full code for anyone to be able to resolve your further error.
