Dear developers,
This morning I compiled gretl from CVS and found a typo in the hansl
primer, section 4.2: Matrix Operations. Oddly enough, the matrix called
*pina* does not produce en error since matrix *a* is 2×2, c=a' is 2×2, and
pina=c+a can be generated from conformable matrices. Maybe you should
change it to pina=b+c in order to demonstrate the non-conformability of a
sum?
