I've seen the matlab path for Statistics (stats), Bioinformatics (bioinfo), Signal Processing (signal).
Error message '??? Reference to non-existent field 'GroupNames' dosen't seem like the absence of toolboxes.
In nets_lda, 'svmStruct.GroupNames' field may be not produced for providing to svmclassify.m
