% Computes missile weight.
This is an alternative to AircraftGroupMassStatement that uses a
different weight model. The model is based on R. Miller's model from
MIT course 16.751. If you enter fileName it will create a file
with a latex table. It is similar to HSVMassEstimation except that
it uses range as an input and does not include landing gear.
Not all values of parameters will produce a feasible design. If the
weight goes to infinity you will need to adjust some of your
parameters. See the demo for a working set of inputs.
