A possible reason behind why the time stamps of outputdata do not match that of the input signal inputdata could be the way in which sampling times are created in MATLAB and Simulink. Assuming the number of samples to be 77312, this is shown below:
dt = 1.25e-8;
t_ML = 0:dt:1.25e-8*77311;
t_SL = [0:1:77311]*dt;
d = t_ML-t_SL;
plot(d)
Please note that t_ML and t_SL do not have the same values, even though mathematically the way they were defined is the same.
Hence, when we attempt to compare the time steps of inputdata which was created from MATLAB and outputdata, which is sampled according to Simulink methods, we notice the difference as above. To avoid this, use the following steps:
1) Define the time values for inputdata in the following way (Simulink approach):
inputdata.time = [0:1:77311]'*1.25e-8;
2) Now run your model to get the values of outputdata
3) Compare the time stamps of inputdata and outputdata:
find(~(inputdata==outputdata))
Note that the output from step 3 will be an empty matrix indicating that the time stamps match.
