◆ hack_size()

template<sp_d data_t, sp_i index_t>
void triplet_form< data_t, index_t >::hack_size ( const index_t  in_elem)
inline

Adjusts the size of the container by reserving space and updating the element count.

This function reserves memory for the specified number of elements and updates the internal element count to match the provided value.

This function is dangerous and should be used with caution. It does not initialize the new elements, and the caller needs to fill them with valid data. Otherwise, the behavior is undefined.

Parameters
in_elemThe number of elements to reserve and set as the new size.

◆ save()

template<sp_d data_t, sp_i index_t>
void triplet_form< data_t, index_t >::save ( const std::string &  file_name) const

Saves the triplet form matrix to a file.

This function writes the matrix data stored in triplet form to a file. The file will contain the number of rows, columns, and non-zero elements on the first line, followed by the row indices, column indices, and values of the non-zero elements on subsequent lines. This follows the Matrix Market (MTX) format.

Template Parameters
data_tThe data type of the matrix values.
index_tThe data type of the row and column indices.
Parameters
file_nameThe name of the file to save the matrix to.
Note
If the file cannot be opened, the function will return without performing any operation.
