That way we will always have it.

I found an example on mat file (ex78) whih can be tested by using .dat file. Since .dat file and .mtx file are similar in structure (specially afiro_A.dat file is similar to amesos2_test_mat0.mtx since they both have 3 columns and the columns represent the same properties), I tried to run ex78 by using amesos2_test_mat0.mtx instead of afiro_A.dat.
