Kotlin Program to Add Two Matrix Using Multi-dimensional Arrays

fun main(args: Array<String>) {
    val rows = 2
    val columns = 3
    val firstMatrix = arrayOf(intArrayOf(2, 3, 4), intArrayOf(5, 2, 3))
    val secondMatrix = arrayOf(intArrayOf(-4, 5, 3), intArrayOf(5, 6, 3))

    // Adding Two matrices
    val sum = Array(rows) { IntArray(columns) }
    for (i in 0..rows - 1) {
        for (j in 0..columns - 1) {
            sum[i][j] = firstMatrix[i][j] + secondMatrix[i][j]
        }
    }

    // Displaying the result
    println("Sum of two matrices is: ")
    for (row in sum) {
        for (column in row) {
            print("$column    ")
        }
        println()
    }
}
 

Output:

Sum of two matrices is:
-2    8    7    
10    8    6
