Comment(by pong):
Hum... sure. For example, something like
def delete_col(A,col_to_del):
cols = list(set(range(A.ncols()))-set(col_to_del));
return A.matrix_from_columns(cols)
will work. I just need to need to recall how to turn that into a method
for matrix. Any pointer for that?
Also, do we want indexing the columns starting from 1 or 0? (the
implementation above assume the index starts from 0).
