There are some strings which might not get freed, but they are very small. How big are we talking?<br>

Hi, Thanks for the quick return on Sunday,<br>
<br>
Here is the result of ex1.c that is mentioned in the previous mail, they are small indeed, but I was wondering if there were still things I could not manage with my pointer allocations/assignments, that is the reason why I made a post.</blockquote>

I also attached another valgrind output, This was just to be sure that I am coding without leaks. BTW, the program seems to work but there are other problems related to eigenvalues I would like to solve for the moment...<br>
