Description

Two new fns rows(M) and cols(M) -- or should its name be columns?

These take a matrix and return a list of lists.

JAA notes that MakeMatByRows and MakeMatByCols take a "flattened" list of entries, so they are not quite inverses to rows and cols.

History

#1 Updated by Anna Maria Bigatti over 5 years ago

I prefer cols (always the same abbreviation).
Or should it be GetCols?
Which name represents better it is making a copy?

There are some functions in CoCoALibSupplement:
  • GetRow_long (indexed from 0)
  • GetRow
  • GetCol
  • GetRows.
    Update also these when making the new functions in CoCoALib.
