ENTRY LINE EDITON

Code:

minor_CAS0(m1):=
begin  
  return(seq(seq(det(delRow(delCol(m1,j),I)),j,1,colDim(m1)),I,1,rowDim(m1)))​​;  
end;

[enter]

then

minor_CAS0([[1,2,3],[4,5,6],[7,8,9]]); [enter] returns
[[-3,-6,-3],
[-6,-12,-6],
[-3,-6,-3]] OK


//////

but HOME MODE

PRG EDITOR

Code:

EXPORT minor_HOME0(m1)
begin
  local out;
  local j:="jj", ii:="ii"; // trick =(
  out := seq(seq(det(delRow(delCol(m1,j),ii)),j,1,colDim(m1)),ii,1,rowDim(m1));
  return(out);
end;

minorHOME([[1,2,3],[4,5,6],[7,8,9]]); [enter] returns "Error: Bad Argument Type" ????
