Hi Guys!
I'm trying to make a sparse matrix where I have 1 1 0 1 1 0 etc as the
off-diagonal entries
So I want something like
i= 1 2 4 5 7 8 ...etc
j= 0 1 3 4 6 7 ....etc
val = 1 1 1 1 1 1
so when I put this in a 9X9 matrix it will go across the diagonal but
will leave a 0 after every two 1 values

Basically, all I need to do for this is create two arrays...one that
skips every multiple of 3n, and one that skips every multiple of
(3n-1). Is there some way to remove all of these 3n, and 3n-1 array
values? I am having a really difficult time finding anything online
that's relatively helpful

Thanks!
