Integration with MATLAB
Define naming convention for input/output parametersInput parameters:
t- Time (vector)y – measurement values (matrix)
Output parameters:Freq – frequency values (vector)Damping – damping values (vector)A – mode shape amplitude values (matrix)theta – mode shape phase values (matrix)
