  1. nma_JacobiIterationMatrixEigenModes.m.txt    (my code)


  1. Also need the file my_xticklabels.m from Matlab central
    http://www.mathworks.com/matlabcentral/fileexchange/19059-myxticklabels  that I used for the setting x-ticks. In case the file goes away, here is a local  copy  my_xticklabels.m.txt
