Error in calling BVP4C(ODEFUN,BCFUN,SOLINIT):
The derivative function ODEFUN should return a column vector of length 8.

In the code you posted above, there is a third free parameter p that is to be adjusted so that all three instead of only two boundary conditions can be satisfied. Your original problem - which you deleted for some resason - did not contain such a free parameter.

The code does not run.
- linspace(0,infinity,40) - what is "infinity" and of course you cannot divide the interval [0, Infinity] into 40 steps.
- The functions need trailing end statements if this is written in a single file.
- You provide an initial value with 8 components, but as the error message tells clearly, shootode replies 7 elements only.

you do not initialize your global variables, so some of your calculations return empty
