I'm not an Origin user, but I'm shopping for analysis and display software. I wondered if Origin does cospectral analysis. For example, suppose I have simultaneous evenly spaced measurements of temperature and pressure. I want to look at the power spectral features of temperature and pressure, separately, and I want to look at the correlation between temperature and pressure as a function of frequency (coherence and phase). Assuming Origin can do that, I wonder if it can also handle the case when the observations are not equally spaced in time (for example, due to missing data points or irregular observation periods).
