To run, simply download the 2 .m files below, put them in the matlab path, and type

 

nma_JacobiIterationMatrixEigenModes.m

 

 

 

Source code

 

  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
