[SciPy-user] optimize.fsolve

Hi,
 
I'm having trouble getting fsolve to work. Does this work in a similar way to matlab's fsolve?
 
I thought I'd start with something really simple, just solving for where two lines cross (y = ax + b - twice). I implemented a function which takes a vector for x and y (ie. say x[0], x[1]) and 'solves' the two equations, returning F[0] and F[1].
 
I then call fsolve on this function... unfortunately it seems to just converge on whatever starting guess I give it, or go to massive numbers!
 
Dave
