"Specify [] for the first dimension to let reshape automatically calculate the appropriate number of rows."
If you specify [] in the second dimention, it will automatically determine the appropriate number of columns for the specified number of rows.

Ah, missed the transpose (the apostrophe) after the first one. That transposes the results of reshape. It's probably just easiest to test it and see:
key = magic(4);
reshape(key,2,[])'
reshape(key,2,[])
Another way is to just swap the 2 and the [].
reshape(key,[],2)

The second creates 2-row matrix.
The first creates 2-column matrix, since it make a transpose after reshape.
