The current version will only function under MATLAB version 6.x

If you use the EMSC toolbox for MATLAB, the author would appreciate a reference to the toolbox and the EMSC/EISC methodology. This may e.g. be

Content
The software provides a number of different method versions, including various automatically optimized versions (Re-weighted EMSC, Simplex-optimized EMSC and Direct Orthogonalization-based EMSC) of the EMSC method and of its sub-methods Spectral Interference Subtraction (SIS) and Extended Inverted Scatter Correction (EISC).
