Go – Program to subtract two matrix in go

Here, we will write a program to subtract two matrix in go. Given below, you can find algorithm and program.

Here, we are going to learn subtractation of two matrix:

  • Take number of rows and columns as input
  • Apply nested for loop to take matrix elements as input
  • Subtract the matrix elements
  • Print the resultant matrix

Example:

Input: row = 2, column = 3

Matrix_1:
[
7, 8, 2
3, 11, 10

]

Matrix_2:
[
1, 2, 3
4, 5, 6
]

Output:
[
6, 6, -1
-1, 6, 4
]

Code:

package main

import (

 "fmt"

)

func main() {

  var row, col int

  var mat_1, mat_2, result [10][10]int

  fmt.Print("Enter no of rows: ")

  fmt.Scanln(&row)

  fmt.Print("Enter no of column: ")

  fmt.Scanln(&col)


  fmt.Println("\nEnter matrix_1 elements: ")

  for i := 0; i < row; i++ {

    for j := 0; j < col; j++ {

      fmt.Scanf("%d ", &mat_1[i][j])

    }

  }

  fmt.Println("\nEnter matrix_2 elements: ")

  for i := 0; i < row; i++ {

    for j := 0; j < col; j++ {

      fmt.Scanf("%d ", &mat_2[i][j])

    }

  }

// Subtracting two matrix

  for i := 0; i < row; i++ {

    for j := 0; j < col; j++ {

      result[i][j] = mat_1[i][j] - mat_2[i][j]

    }

  }

  fmt.Println("\nAfter Subtracting Matrix is: \n")

  for i := 0; i < row; i++ {

    for j := 0; j < col; j++ {

      fmt.Printf("%d ", result[i][j])

    }
    fmt.Println("\n")

  }

}

Output:

Enter no of rows: 2
Enter no of column: 3

Enter matrix_1 elements:
7
8
2
3
11
10

Enter matrix_2 elements:
1
2
3
4
5
6

After Subtracting Matrix is:
6 6 -1
-1 6 4
