A set of functions to automatically process files saved by Avantes AvaSoft 7 software. See demo for example of use and descriptions within each m-file. The main function to use is avantesSpectrumRead, it will read all binary and ASCII files saved by Avantes within a directory. The binary file reader is the avantesBinaryRead function. A couple of additional useful functions (getScansByTime and getValueAtWavelength) are provided.
