I am trying to isolate the negative eigenvalues and store them an an array with their corresponding eigenvectors in another array. I uderstand I need to use the eig function and i believe a for loop needs to be used to go through all of the eigenvalues but I can't figure out how to isolate the negative values in an array and get the eigenvectors that corrospond with those negative eigenvalues in an array. Any help is appreciated
eigenvalue = eig(Z);
[EigenVector,D] = eig(Z);

Hi
These lines of code can be used by you:
negEigenInd = find(eigenvalue< 0); %Indices
reqEigenVector = EigenVector(negEigenInd);
reqEigenvalue = eigenvalue(negEigenInd);
Hope this helps!
