Creating a matrix with values in Kotlin in convenience

Issue

I want to create the following one with a fancy notation:

arrayOf(intArrayOf(4, 5), intArrayOf(5, 8), intArrayOf(1, 9), intArrayOf(8, 10), intArrayOf(1, 6))

at least, cannot I achieve something that looks as follows:

arrayOf<IntArray>((4, 5), (5, 8), (1, 9), (8, 10), (1, 6))

because it is pretty awkward to rewrite intArrayOf for each row to put in.

Note that I do not ask for the following syntax I'm aware of which is used to initialize an empty matrix with values that are either same or following a common pattern.

val array = Array(row) { IntArray(column) }

Solution

If you simply don't like the wordiness of using intArrayOf you could define a shorter name to do the same, for example

fun i(vararg e: Int) = intArrayOf(*e)

And then do

arrayOf(i(4, 5), i(5, 8), i(1, 9), i(8, 10), i(1, 6))
