Having problems transposing a large vector.

I came across a puzzling issue today. When trying to transpose a column vector (86400048x1) into a row vector, MATLAB seems to transpose the vector (variable shows up as 1x86400048), but the vector does not show up when I select the variable. The area where matrices usually show up is simply empty. To troubleshoot, I tried to index out portions of the vector (split into ten ~equal pieces), and then combine each piece again. I was able to combine the vector to get a 1x85000000 row vector, but can't add much more without the same issue occurring. Any ideas as to what is going on here?

Are you referring to the Workspace Browser?

How much RAM do you have on your machine?

I see you have a (659 MB) ~3/4 GB vector in memory if all this is native double type vector.

Maybe this is causing some display issues ?

But a screenshot maybe useful here.

I can reproduce (on R2013b,32GB,64bit) the problem you see. Rows exceeding a certain size are not displayed in the "Variables editor". In my case r2 is shown, r4 is not. And the column vector, c2, is not shown

c2        172800096x1                   1382400768  double              
r2                1x17280008             138240064  double              
r4                1x34560016             276480128  double

I fail to find upper limits mentioned in the documentation. However, there are obviously such limits.
