Solving unknowns of kinematic equations in octave.

[ZachTM]

Hello I am fairly new to octave but I have been playing around with fsolve. 
I want to make an octave program that can solve for the 5 possible unknowns
in the kinematic equations. (vi,vf,a,d, and t)

Would it be possible to somehow define these equations:
<http://octave.1599824.n4.nabble.com/file/n4652529/KE1-3.jpg> 
And then when I define 3 or more of the variables it could solve for the
other two?  I just dont know how I would get this to work with fsolve.  I
could make an octave program that picks which equation it will use for every
unknown but I would like to extend this to work with any set of equations
and unknowns (within reason of course).  If the user doesn't give enough
variables I would return an error.

So can anyone tell me if this would be even possible?  And if fsolve would
be appropriate to use here?  Any responses are greatly appreciated!

Thanks,
Zach
