Hi there, perhaps someone has a bright idea for this one:
I want to concatenate ranges of numbers into a single array (for indexing). So I have generated an array "a" with starting positions, for example: a = [4, 0, 11] I have an array b with stop positions: b = [11, 4, 15] and I would like to generate an index array that takes 4..11, then 0..4, then 11..15. In reality, a and b have 10000+ elements and the arrays to be "sliced" are very large so I want to avoid any for loops etc. Any idea how this could be done? I thought some combination of *repeat* and adding of *arange* should do the trick but just cannot nail it down. Thanks in advance for any hints!
