library(Matrix)

# Ukuran matriks
baris <- 3
kolom <- 3

# Matriks pertama
A <- matrix(c(1, 2, 3, 4, 5, 6, 7, 8, 9), nrow = baris, ncol = kolom)

# Matriks kedua
B <- matrix(c(10, 11, 12, 13, 14, 15, 16, 17, 18), nrow = baris, ncol = kolom)

# Inisialisasi matriks hasil
C <- matrix(0, nrow = baris, ncol = kolom)

# Penjumlahan matriks
for (i in 1:baris) {
  for (j in 1:kolom) {
    C[i,j] <- A[i,j] + B[i,j]
  }
}

Output program ini akan menampilkan tiga matriks, yaitu matriks A, matriks B, dan hasil penjumlahan matriks A dan B.

# Menampilkan hasil
print("Matriks A:")

## [1] "Matriks A:"

print(A)

##      [,1] [,2] [,3]
## [1,]    1    4    7
## [2,]    2    5    8
## [3,]    3    6    9

print("Matriks B:")

## [1] "Matriks B:"

print(B)

##      [,1] [,2] [,3]
## [1,]   10   13   16
## [2,]   11   14   17
## [3,]   12   15   18

print("Hasil penjumlahan:")

## [1] "Hasil penjumlahan:"

print(C)

##      [,1] [,2] [,3]
## [1,]   11   17   23
## [2,]   13   19   25
## [3,]   15   21   27
