Abstract: Root of characteristic equation for cylindrical Bessel equation eigenvalue prob- lems on general interval is of great real physical importance at engineering and physical. First, the characteristic equation of cylindrical Bessel equation eigenvalue problem on general interval is given, second, by mean of compared method, we obtaining roots of characteristic equation with Matlab program is discussed.

Key words: cylindrical Bessel equation, characteristic equation, method of Matlab
