You store the code in a file named my_imresize.m

You can't have a script and a function inside the same m-file. You can have two functions and they don't need to be nested . For example if your m-file is called test.m, you could have test() and Ray() both inside test.m like this:

function test()
a = 0.5;
B = 0.6;
k = 1; 
[t, x] = ode45(@Ray, [0 30],[ 0 0.1], [], a, B, k); 
plot(x(:,1), x(:,2), 'k-') 
function d = Ray(t, y, a, B, k)
d=[y(2);-k*y(1)+a*y(2)-B*y(2^3];

MATLAB: What is meant by Error: Function definitions are not permitted in this context

The error means that you are not permitted to define a function file inside a script file. Create your ‘facetest’ as a separate file in the MATLAB Editor(open a new tab) and then save it as facetest.m. See the documentation on Function Basics for details.
