(having a matrix selected)
(matdim is a variable = matrix dimension)

- mat2list (M) ;-)
- apply QPI program ;-)
- list2mat (M, matdim)
- results (again the matrix but with QPI applied)

:-)

Thank you in advance!

Code:

#cas
qpimat(m):=
BEGIN
  local s:=dim(m);
  m:=mat2list(m);
  m:=QPI(m);
  m:=list2mat(m,s(2)); 
  return m;
END;
#end

Create a new program named qpimat and make sure it's a CAS program. Then type in the code above. Note that you must be in CAS view in order to see symbolic matrices. In Home view, qpimat does nothing.
