The pspectrum function was released in R2017b.Depending on what you want to do, use the spectrogram (link) function or the the pwelch (link) functo to get the power spectral density. If you want to look at your signals before and after filtering, see: Power Spectral Density Estimates Using FFT …
Frequency resolution bandwidth, specified as the comma-separated pair consisting of 'FrequencyResolution' and a real numeric scalar, expressed in Hz if the input contains time information, or in normalized units of rad/sample if not. This argument cannot be specified simultaneously with 'TimeResolution'.
