A function for calculating the natural frequencies and mode shapes for an elastic beam supported by end springs is included in:
Matlab script: Vibrationdata Signal Analysis Package
The function can be accessed via:
>> vibrationdata > Miscellaneous > Structural Dynamics > Beam Bending > Beam with End Springs, FEA
Options for calculating the beam response to an applied force will be added soon.
