Example 3 Construct a 3 ร 2 matrix whose elements are given by aij = 1/2 |๐โ3๐|. Since it is 3 ร 2 Matrix It has 3 rows and 2 columns Let the matrix be A where A = [โ 8(๐_11&๐_12@๐_21&๐_22@๐_31&๐_32 )] Now it is given that aij = 1/2 |๐โ3๐| Hence the required matrix is A = [โ 8(๐_11&๐_12@๐_21&๐_22@๐_31&๐_32 )] = [โ 8(1&5/2@1/2&2@0&3/2)]
