MAT file format
  • The *mat-file provides essentially the same information as the *fsp ascii-file, saved in a convenient and user-friendly MATLAB-structure. Type 'load evTAG.mat at the MATLAB-prompt (replace evTAG with the model name), and you will get a structural array of the corresponding model. The various structural fields are labeled in a self-explanatory manner (at least I hope so); field-names in these structures are often similar to the parameters described for the *fsp-file format.
  • An example for the 1992 Landers earthquake (model by Wald et al, 1993) is given below; for other events or rupture models, the details of the MATLAB-structure may vary, while only the initial parts are unchanged:
