the location based collaboration, the change of the spatio- temporal relationship of the people-people or people-place is the key context for collaboration. So, the location based collaborative environment should support the spatio-temporal event sub/pub service. The key problem in spatio-temporal event subscription is how to specify the different spatio-temporal events.

In MATLAB, usually we use function bvp4c() to solve boundary value problem (BVP) of ODE. However, we also can use function ode45() to solve BVP of ODE too. However, ode45() needs all initial values at one point. Therefore we have to construct an auxiliary function, whose input argument is the missing initial value and the return output is the given boundary value, Then we can call function fsolve() to get the missing initial value. This method is particularly efficient it the ODE has one or more parameters. Also this method is essentilal for GNU Octave, because whose function bvp4c() is not programmed for parameter ODE yet.
