Hi
In my program, i use the function eig to return the eigenvalues :
[V,D]=eig(k,m);
But i have obtained this error:
Error using eig
EIG does not support generalized eigenproblem EIG(A,B) when A or B is sparse.
Please help me.

Clearly you need to give us more information on k and m. Judging from the error messages though it seems clear that one of your two inputs, k or m, are sparse matrices and these are not supported by Eig.

According to the sparse matrix section of the documentation, you need to use the eigs function.

They seem to, but the results of eig are ordered opposite those of eigs. The eigs funciton works with sparse matrices, while eig does not.
Check them with something like this example (not using sparse matrix arguments):
A = randi([-9 9], 5);
[V1,D1] = eig(A)
[V2,D2] = eigs(A)
