I have attatched simple scripts which should work in 'octave' http://www.che.wisc.edu/octave (perhaps Matlab too - don't know though - if you run Matlab please inform your parents) The scripts will find ERBs from Frequencies and vica versa. Once in the ERB domain harmonics are equidistant in range (in theory any way). But I'm sure someone else will want to expand on this point .... There are some papers by Greenwood for example which will tell you that what is reguarded a harmonic is different for different mammals ...
