I am a new MATLAB user, so I would like to plot Acceleration vs Time plot, Acceleration vs Frequency to interpret the FFT results of a structural vibration problem. I have data such as acceleration and time in "mat" format, the file which consist of acceleration results indicates "Cannot display summaries of variables with more than 524288 elements" when I try to open it. So I have no idea how to start. I would appreciate if somebody helps me. Thank you for understanding!
