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.
