The Matlab scripts vc_velox.zip calculate the one-third octave band velocity spectrum of a time history for comparison with ISO Generic Vibration Criteria for Vibration-Sensitive Equipment.
The main script is: vc_velox.m
The remaining scripts are supporting functions.
The input file may either be an acceleration or velocity time history.
The scripts are useful for evaluating measured floor vibration in semiconductor fabs, laboratories, theaters, etc.
A Matlab GUI version is included in: Vibrationdata Matlab Signal Analysis Package
