I think you want to calculate the eigen values the Jacobian matrix for the AC-DC power flow. You need to get in touch with MATACDC developers to find out what API is provided for obtaining the Jacobian matrix. MATPOWER has the function makeJac() http://www.pserc.cornell.edu/matpower/docs/ref/matpower5.0/makeJac.html for returning the power flow Jacobian. MATACDC should be having something similar. Once you get the matrix, MATLAB has eigen value solver (help eigs) that you can use to calculate the eigen values.
