Re: help to programm

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 ???
