Creating a matrix with values in Kotlin in convenience<p>I want to create the following one with a fancy notation:</p> <pre><code>arrayOf(intArrayOf(4, 5), intArrayOf(5, 8), intArrayOf(1, 9), intArrayOf(8, 10), intArrayOf(1, 6)) </code></pre> <p>at least, cannot I achieve something that looks as follows:</p> <pre><code...
<p>If you simply don't like the wordiness of using <code>intArrayOf</code> you could define a shorter name to do the same, for example</p> <pre><code>fun i(vararg e: Int) = intArrayOf(*e) </code></pre> <p>And then do</p> <pre><code>arrayOf(i(4, 5), i(5, 8), i(1, 9), i(8, 10), i(1, 6)) </code></pre>
