The Engineering Vibration Toolbox is a set of educational programs written in Octave by Joseph C. Slater. Also included are a number of help files, demonstration examples, and data files containing raw experimental data. The codes include single degree of freedom response, response spectrum, finite elements, numerical integration, and phase plane analysis.
