How can I delete a column/row from a matrix.
As an in-place operation, not at all. To get a copy of an array
with some
columns/rows removed, use Numeric.take.
The in-place operation of matlab is a nice feature. Is it thinkable to have this in scipy or numarray at a later date ?

Speaking for numarray, no, not really. But I wonder what is really done for matlab. Either they have a more complex representation of arrays, or all they really are doing is making a new copy of the array and giving you the impression it is being done in place. After all you are changing the size and structure of the array. Perry
