Can anyone please tell me which is the algorithm that Matlab uses for computing Eigen values and Eigen vectors when I use the command:
[V,D]=eig(K,M);
Where am I defining the algorithm type here?

Dear Sir,
Please have a look at the documentation
Here you can find the following line:
"[___] = eig(A,B,algorithm), where algorithm is 'chol', uses the Cholesky factorization of B to compute the generalized eigenvalues. The default for algorithm depends on the properties of A and B, but is generally 'qz', which uses the QZ algorithm. If A is Hermitian and B is Hermitian positive definite, then the default for algorithm is 'chol' ."
Also you could type in MATLAB: >> edit eig
Kind regards, Christiaan
