Wow. It is fast. Can someone change the output of tread to be a matrix
for numbers instead of a cell (see below)?
That shouldn't be too hard. One must just modify the function
set_cell_data to accept two template arguments in stead of one: a
container_type and a column_type.
The only thing that might be tricky is keeping track of all the output
matrices. I thought I could do this using an octave_value_list, but
it's not so easy to get to the actual representation of an octave_value.
E.g., in the case of a matrix, we need to reach the octave_value's
internal matrix representation (without making any copies of the
matrix in memory).
Alternatively, we can keep a list of void pointers, but that seems
like the dirty (dangerous) way of doing things.
If anyone knows how to handle this problem, I'll be glad to know.
("This problem" referring to keeping a list of differently typed
objects, while retaining the ability to access the objects).
