Reading .mat files

Under SAMPLE OUTPUT, you can download the following: MEDLINE: term-document matrix (5,735 x 1,033), dictionary (5,735 indexing terms), query matrix (30 queries)
They are all in .mat format.
When I import the matfiles in Matlab, it says e.g. A_med<5735x1033 double>
But when I do something like: A = A_med(1:10,1:10)
It is displayed as: A =
(3,2) 2
(4,2) 2
(8,2) 2
(6,6) 1
What format is this really?

That display is used for sparse matrices. Sparse matrices are (in current versions) restricted to double precision, or logical.
You can use issparse() to determine whether a matrix is sparse or not.
