Dear List,
I was looking through the Macsyma User's Guide, second edition, pp. 120-123, and noticed some very
useful features for extracting parts of a matrix. For example, the sequence operator .. is used as
follows, A[..,3], A[2,..], A[..,1..4], A[1..2,3..6], etc.
Any assistance in implementing the above features would be appreciated.
Thanks very much,
Constantine Frangos.
