I think you wanted  prototype:protoCell  here

1) This isn't FORTRAN.  The first cell is 0:0, not 1:1.
2) SelectionCells don't have titles, they have stringValues.
   say  [[myMatrix cellAt:0:0] setStringValue:"first"];
				(or setStringValueNoCopy:"first")
   Note that Matrix doesn't implement setStringValue:at:, only
   Form does, and Forms can only have one column, so there's no
   setStringValue:at::, hence the use of cellAt::.
