Kotlin Program to Multiply to Matrix Using Multi-dimensional Arrays
Source Code
fun main(args: Array<String>) {
val r1 = 2
val c1 = 3
val r2 = 3
val c2 = 2
val firstMatrix = arrayOf(intArrayOf(6, -1, 5), intArrayOf(2, 0, 6))
val secondMatrix = arrayOf(intArrayOf(7, 4), intArrayOf(-2, 0), intArrayOf(0, 4))
// Mutliplying Two matrices
val product = Array(r1) { IntArray(c2) }
for (i in 0..r1 - 1) {
for (j in 0..c2 - 1) {
for (k in 0..c1 - 1) {
product[i][j] += firstMatrix[i][k] * secondMatrix[k][j]
}
}
}
// Displaying the result
println("Product of two matrices is: ")
for (row in product) {
for (column in row) {
print("$column ")
}
println()
}
}
