Hi all, Does anyone know how to insert and delete a range of rows and/or columns in the multiarray class documented at http://www.boost.org/libs/multi_array/doc/ ? What performance guarantees can I expect for these operations ? I'm a little pressed for time and haven't been able to figure out how to do this on my own. The statement that "The number of elements will remain fixed for the duration of a multi_array's lifetime" on the documentation page suggests that these operations may not even be supported, but I'm not sure if I'm misunderstanding the statement or not. Thanks a lot. -------------------------------------------------------- Mike Adewole ACNielsen, Global Decision Support Services ph: 905-475-3344x2411 fx: 905-475-8357 mike.adewole@acnielsen.ca --------------------------------------------------------
