給定兩個矩陣 MAT1[行][列] 和 MAT2[行][列],我們必須找到兩個矩陣之間的差異並列印兩個矩陣相減後獲得的結果。兩個矩陣相減為 MAT1[n][m] – MAT2[n][m]。
對於減法,兩個矩陣的行數和列數應該相同。
Input: MAT1[N][N] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9}} MAT2[N][N] = { {9, 8, 7}, {6, 5, 4}, {3, 2, 1}} Output: -8 -6 -4 -2 0 2 4 6 8
下面使用的方法如下 -
我們將為每一行和每一列迭代矩陣,並從mat1[][]中減去mat2[][] 的值並將結果儲存在result[][] 中,其中所有矩陣的行和列保持相同。
In fucntion void subtract(int MAT1[][N], int MAT2[][N], int RESULT[][N]) Step 1-> Declare 2 integers i, j Step 2-> Loop For i = 0 and i < N and i++ Loop For j = 0 and j < N and j++ Set RESULT[i][j] as MAT1[i][j] - MAT2[i][j] In function int main() Step 1-> Declare a matrix MAT1[N][N] and MAT2[N][N] Step 2-> Call function subtract(MAT1, MAT2, RESULT); Step 3-> Print the result
即時示範
#include <stdio.h> #define N 3 // This function subtracts MAT2[][] from MAT1[][], and stores // the result in RESULT[][] void subtract(int MAT1[][N], int MAT2[][N], int RESULT[][N]) { int i, j; for (i = 0; i < N; i++) for (j = 0; j < N; j++) RESULT[i][j] = MAT1[i][j] - MAT2[i][j]; } int main() { int MAT1[N][N] = { {1, 2, 3}, {4, 5, 6}, {7, 8, 9} }; int MAT2[N][N] = { {9, 8, 7}, {6, 5, 4}, {3, 2, 1} }; int RESULT[N][N]; // To store result int i, j; subtract(MAT1, MAT2, RESULT); printf("Resultant matrix is </p><p>"); for (i = 0; i < N; i++) { for (j = 0; j < N; j++) printf("%d ", RESULT[i][j]); printf("</p><p>"); } return 0; }
如果執行上面的程式碼,它將產生下列輸出-
Resultant matrix is -8 -6 -4 -2 0 2 4 6 8
