Note:      Singularities, caused by linear dependance, can be circumvented
 
30
           by first carrying out a PCA, and using a small number of principal
 
31
           components as input to LDA.
 
32
           Singularity problems may arise in matrix inversion, due to
 
33
           very small values: if you get an IERR=2 message, multiplying
 
34
           the input data by an arbitrary constant may painlessly get
 
35
           around the difficulty.
