I was looking for a function to return the capacity of a Boost uBLAS map_array, so I checked the docs online. When I looked at this page: https://www.boost.org/doc/libs/1_67_0/libs/numeric/ublas/doc/index.html I found in the table of member functions two entries for the size() function, but one should clearly be the capacity() function. I confirmed in our headers that it exists. -- Dick Hadsell 203-992-6320 Fax: 203-992-6001 Reply-to: hadsell@blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 1 American Lane, Greenwich, CT 06831-2560
