Hello,
Sorry, but I don't understand your formula. Maybe it's better if you
1. use * for multiply.
2. break the expression into smaller components. For instance,
(Is it an add and a multiply or two multiplies?)
EXP <- exp{ (B0 B1 row matrix) (z[l] column matrix) }
Then use EXP.
3. instead of 'row matrix' write 'row_matrix', the same for column matrix.
4. Your final sum is the sum of what ???
