Java Program to determine whether two matrices are equal

Java Program to determine whether two matrices are equal

In this program, we need to check whether given matrices are equal or not.

Two matrices are said to be equal if and only if they satisfy the following conditions:

• Both the matrices should have the same number of rows and columns.
• Both the matrices should have the same corresponding elements.

Consider the above example, where matrices A and B are equal as they have the same size and same corresponding elements.

Algorithm

• STEP 1: START
• STEP 2: DEFINE row1, col1, row2, col2
• STEP 3: INITIALIZE first matrix a[][] ={{1, 2, 3}, {8, 4,6}, {4, 5,7}}
• STEP 4: INITIALIZE second matrix b[][] ={{1 2, 3}, {8, 4, 6}{4, 5, 7}}
• STEP 5: row1 = a.length
• STEP 6: col1 = a[0].length
• STEP 7: row2 =b.length
• STEP 8: col2 = b[0].length
• STEP 9: if(row1!=row2 || col1!=col2)
          then
          PRINT “No”
          else
          go to step 10;
• STEP 10: REPEAT STEP 11 UNTIL i<row1
          //for(i=0; i<row1; i++)
• STEP 11: REPEAT STEP12 UNTIL j<col1
          //for(j=0; j<col1; j++)
• STEP 12: if(a[i][j]=b[i][j]) then
          flag =false
          break
• STEP 13: if(flag)
          then PRINT “Yes”
          else
          PRINT “No”
• STEP 14: END

Output:

Matrices are equal
