Non-linear shot

Solves linear and non-linear boundary problem using shot method (secant or Newton)

Contains seveal files which function is explained on coments inside each of them. Just note that although both dispnolin and disponlinewt can solve roughly the same problems, the later should converge more quickly given that it uses Newton method. To work with disponlin use u.m and v.m, to work with dispnolinewt use fy.m and fym.m
Rungkutm.m is just there to solve initial value problems, but you can use it all alone for that pourpose too if you want.
