示例1: reset_nocopy
/**
* WARNING: Only use this method if you know what you are doing!
*
* This deallocates any data currently in this matrix.
* It then takes the data from the given arguments;
* this transfers ownership of the data to this class,
* clearing the data from the given arguments.
* This permits piecemeal construction of a CSC matrix without
* unnecessary reallocation.
*
* @param new_row_indices WARNING: These MUST be sorted in increasing
* order (for each column).
