| void g2o::MatrixStructure::alloc | ( | int | n_, |

| ) |
allocate space for the Matrix Structure. You may call this on an already allocated struct, it will then reallocate the memory + additional space (double the required space).

| bool g2o::MatrixStructure::write | ( | const char * | filename | ) | const |
Write the matrix pattern to a file. File is also loadable by octave, e.g., then use spy(matrix)
