This Smath document works well, but NOT by itself !
Welcome Collabs/Designers for doctoring the patient.


Inconvenience/alternative:
Algorithm Center(M) does NOT support:
1. calculated matrix 'Convol',
2. 'Convol' spooled to file,
3. assigned Ni,j from dual "forloop"
Center(M) takes ONLY an existing matrix
Expand Convol => paste in collapsed.
