# EndpointRanges

This Julia package makes it easier to index "unconventional" arrays

(ones for which indexing does not necessarily start at 1), by defining

constants `ibegin` and `iend` that stand for the beginning and end,

respectively, of the indices range along any given dimension.

# Usage

```jl

using EndpointRanges

a = 1:20

a[ibegin:iend] == a

a[ibegin+3:iend-2] == a[4:18]

a[1:(ibegin+iend)÷2] == a[1:10]

```

Note that, unlike `3:end` you can also pass such indices as arguments to a function:

```

view(a, ibegin+2:iend-3) == view(a, 3:17)

```
