<div dir="ltr">To clarify : <br>The data from xxd -b petsc_output_dat is what I've reordered. The binary dump is confusing to read since it contains 6 bytes per line (alongside the unnecessary ascii conversions) and the numbers start and end in odd places. I wanted each line to have only one number and copy pasted the data into a new file. Then I changed the spacing so that the first two lines have 4 bytes (corresponding to int-32) each and correspond to VEC_FILE_CLASSID and num_elements (20 in this case). This is followed by 8 bytes (64-bit double) per line which store the actual elements of the vector.<br><br></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Dec 5, 2018 at 12:57 PM Sajid Ali <<a href="mailto:sajidsyed2021@u.northwestern.edu">sajidsyed2021@u.northwestern.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>It's just a cleaner re-write of the petsc output that I can understand (which I intend to modify from python in the future).
