Where is the NMR?

A big difference between working with matNMR and other NMR processing packages is that the user doesn’t NEED to work with typical NMR parameters like spectral width, the carrier frequency, etc while processing. Naturally that comes from the fact that MATLAB doesn’t know NMR, only matrices, vectors and numbers, and also matNMR doesn’t care really about the NMR behind a FID, i.e. every axis plotted below a spectrum is given in points unless a different axis is defined. Having said that, matNMR does show the typical NMR units if wanted and if the relevant parameters have been supplied correctly. If the spectral width and the spectral frequency for a certain dimension have been supplied (either during loading of a binary FID or manually, then the default axis, see also paragraph 2.2.1 General Options, will produce proper time and frequency axes (Hz or PPM). The reference for such frequency axes is always set to 0 and in the center of the spectrum. NOTE that by changing the spectral width a
