Hi, Eike,

During import when the matrix formula cell is encountered,

ScMyTables::AddMatrixRange->ScDocument::InsertMatrixFormula calls

ScFormulaCell::SetMatColsRows then (InsertMatrixFormula) sets the matrix

formula cell (top left) and then the matrix reference cells.

. After this, the top left matrix formula result is set with

ScFormulaCell::SetHybridString or SetHybridDouble. As the matrix

reference cells are encountered during import, their result is also set

with ScFormulaCell::SetHybridString or SetHybridDouble.
