A symmetric matrix A is a square matrix that is equal to its transpose.
Note that only square matrices can be symmetric. Another condition is that A(i,j)=A(j,i) for all i and j.
Write a matlab function called testsym that returns, for an input matrix A, an output y = 1 if the matrix is symetric and 0 otherwise
