a code to verify a matrix is symmetric in matlab

You can verify a matrix is symmetric or not by comparing it with its transpose. If the original matrix A is symmetric, then A = A' should be true.

Here's the code to check a matrix is symmetric in MATLAB:

main.m
function [isSymmetric] = isMatrixSymmetric(A)
% Returns true if a matrix is symmetric, false otherwise.
isSymmetric = isequal(A, A.');
end

To use this function, call isMatrixSymmetric(A) with your matrix A as an argument. The function will return true if the matrix is symmetric, and false otherwise.
