LTPDA Toolbox™ |
contents |

Up to now, all the activity of the tutorial has been carried out on the MATLAB command terminal. It is, of course, much more convenient to collect the commands together in to a MATLAB script. In this sense, LTPDA scripting is just the same as normal MATLAB scripting; just using LTPDA commands.

Here's an example script which makes two white-noise time-series and estimates the power-spectral-density of each.%% Make two test AOs a1 = ao(plist('tsfcn', 'randn(size(t))', 'fs', 10, 'nsecs', 100)); a2 = ao(plist('tsfcn', 'randn(size(t))', 'fs', 10, 'nsecs', 100)); %% Make PSD Estimates psds = psd(a1, a2); a1xx = psds(1); a2xx = psds(2); % The following also works. b1xx = psd(a1); b2xx = psd(a2);

You can explore the commands used to rebuild the object by using the `type`
method. Or you can inspect (with `type` or `viewHistory` the history as we did earlier. For example, try this command
for each of the cases above:

type(a1xx) type(b1xx)
