MATLAB: Data accuracy

Question

hi everyone…

i just wanna ask, is it possible to get data accuracy more precise than the time step. for example, in some simulation we set the step to be 1 second but in the sample time we want to get the data accuracy every 0.01 second, so it means 100 data during the 1 second step. can we???

thank you

best regards

Answer 1

No, the best you would be able to do would be to interpolate the values at the intermediate times, which is not going to be any more accurate than the way-points, and is going to be less accurate unless the interpolation function matches the underlying equations.

If you need accuracy to 0.01 then use that as your time-step.
