The function generates pseudo-spectral acceleration (PSA), pseudo-spectral velocity (PSV) and spectral displacement (SD) spectra for given damping ratio (e.g., 5% of critical). Spectral ordinates are for linear-elastic single-degree-of-freedom system with unit mass. A clear example is provided in demo.m file in zipped folder. Also provided is a plotting function for PSA, PSV and SD spectra.
