I am new to MATLAB and I facing the following trouble-

I have a 2 dimensional array (termed as trajectories). It has 7808 rows and 2 columns. I want to view it!

The command : trajectories(:,:,1) or trajctories(:,:,2) is not helping as I get about 5000 rows and not the full array.

Also can I save these as 2 excel files?

Please help!

Thanks in advance, Ishani

How do you want to view it? As text?

trajectories(:,1) should display the first column. However it is possible that your MATLAB is configured to only save the last 5000 lines of output.

Preferences -> Command Window -> Display (block on right side) -> Number of lines in command window scroll buffer

Thank you very much!

x = trajectories(:,1) ; 
y = trajectories(:,2) ; 
plot(x,y)

Thank you!

is there a way I can save the trajectories in two excel files?

Let T be your n*2 array.

writetable(T,'test.xlsx');
