This "marker" terminology coming from CMR is terrible. Can we find a better name for these arguments?

How about using col_index, row_index?

Check how methods such as submatrix and matrix_from_rows_and_columns call their arguments

I change it to column and row following the arguments in submatrix
| row_subdivision.append(second._mat.numRows) | ||
| column_subdivision.append(first._mat.numColumns) | ||
| column_subdivision.append(second._mat.numColumns) | ||
| CMR_CALL(CMRtwoSum(cmr, first._mat, second._mat, first_marker+1, -(second_marker+1), &sum_mat)) |

This encoding of row and column indices is an implementation detail.
Better to use these functions:
CMR_ELEMENT CMRrowToElement(size_t row)
CMR_ELEMENT CMRcolumnToElement(size_t column)

Got it. I will change it. By the way, what does the sum.subdivide() do? I don't understand its function and just copy it from the one_sum function

this is what creates the horizontal and vertical lines in the print representation of the matrix
