Concatenating a 3D matrix in the 3rd dimension when some cells are empty

I have a 3D cell array 'A' of size 120 x 180 x 365 (latitude, longitude, day of year).
If I call up a single cell (e.g. A(1,1,1)), this opens matrix 'B' which has two columns (vessel identity, speed), but the number of rows varies by cell. Some cells do not contain any data and display [ ] instead of a B matrix.
I need to make one B matrix that displays all the vessel identities and speeds for A(1,1,1:365)
How can I vertically concatenate matrix B in the third dimension?
Thank you for your help.

B = cat(1,A{1,1,1,:}) % N-by-2 array

You said that opening up a single element A(1,1,1) results in a B matrix with two columns. But A{1,1,1} is returning a 1 x 18 cell array. There is a contradiction here.
