<div><br>
</div>
<div>I am trying to load matrix in Matrix Market format. 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. However, I got the error "Badly formatted input file". Here is the full error message:</div>

<div>I know there is also an example (ex72) for Matrix Market format but in description, it is only proper for symmmetric and lower triangle, so I decided to use ex78.</div>
