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

nma_JacobiIterationMatrixEigenModes.m

Source code

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
