[ISC Practical 2014] In other words, we can say that matrix A is said to be skew-symmetric if transpose of matrix A is equal to negative of Matrix A i.e (A T =−A).. Another quite interesting opportunity is based on the following mathematical fact: if A is some matrix, then A multiplied by its transpose is always symmetric. Viewed 7k times 0. A Skew Symmetric Matrix is the one that is negative of its Transpose Matrix. Next in the same row we have indexing value of column is 2 and value is 4. IN JAVA: A matrix is said to be symmetric if it is square (has same number of rows/columns) and equal to its own transpose (the matrix with its rows and columns switched). ...

ISC 2014 [Question 2] Practical Paper Solved – Symmetric Matrix Java program to accept a 2D matrix of size 'MxM' and check whether it is Symmetric or not. Since real matrices are unaffected by complex conjugation, a real matrix that is symmetric is also Hermitian. In the last row (of 4 X 4 matrix) that is R3, column 1 value is 3. A square matrix, A, is skew-symmetric if it is equal to the negation of its nonconjugate transpose, A = -A. Note that all the main diagonal elements in the skew-symmetric matrix are zero. And then compare the actual array and the transpose, if both the matrices are the same then the matrix is symmetric.
