When running the following code no output (graph) is given, instead matlab gives 'busy' in the bottem left hand corner. Any ideas?
if (x<=-d)
a = -g -s1*x/m_c -v*c/m_c + s2*x/m_c;
else a = -g -s1*x/m_c -v*c/m_c;
end
x = x + v*dt;
v = v + a*dt;
Disp(i)=x;
Vel(i)=v;
t=t+dt;
Time(i)=t;
i=i+1;
end
end

if (x<=-d)
when that is true, you do not change t, and you get caught in an infinite loop.
Perhaps you want an "end" immediately after the second assignment
if (x<=-d)
a = -g -s1*x/m_c -v*c/m_c + s2*x/m_c;
else
a = -g -s1*x/m_c -v*c/m_c;
end
