I have managed to come up with a solution, just in case anyone has this problem again.
Firstly, I enabled Single Simulation output in the Configuration Parameters in Simulink.
Secondly, I was then able to use the following
t = out.simout.time(out.simout.time >=0.1); % get time from out.simout where time >= 0.1
Vce = out.simout.data(out.simout.time>=0.1,1); % get data from data where time >= 0.1
