Using vectorized solve block to solve for multiple inputs.

Hello,

I am trying to use a solve block to solve the same equation for a range of inputs using the vectorize function. I have had success doing this before (thanks to other threads I have read here!). For some reason on this particular problem I cannot get it to work. If someone might have any suggestions after looking at the attached worksheet it would be great appreciated. In the worksheet I first solve the problem for a single input which works, then I try the multiple inputs but can't get the solver to return anything other than the inital guess.

Thanks,

Mike Einhorn
