Shooting method with ODE23 and FZERO for nonlinear BVP

[arditi]

need help please having a problem with shooting mthd

i am having a problem coding a MATLAB code for the given eqn

d^2T/dx^2 - 1*10^-7(T+273)^4+4(150-T)=0
BC T(0)=200 and T(0.5)=100

the differential equation should be solved by
the function ODE23, and the consistent initial condition should be found by the
function FZERO in Matlab. I have to reduce the problem to a root finding
problem somehow, but i just can't do it.
please help me

Welcome to PhysicsForums!

I myself am hazy on the Shooting Method, but you may want to start here (or in your notes / textbook):
