How can I save values in a matrix?

I was asked to create a simulation of an airflight, in three steps:(The problem is in the third step, the first two functions work properly. However, I'm including them for better understandment)

Step 1:

 function failure= SimEngine(x)

 n=rand(1,1);

 if (n<x)

 failure=true;

 else failure=false;

 end

 end

Step 2:

 function crush= SimAirplane(a,x)

 m=0;

 for i=1:a

 A=SimEngine(x);

 if (A==1)

 m=m+1;

 end

 end

 if (m>(a/2))

 crush=true;

 else 

 crush=false;

 end

 end

So in the third step, I was asked to use the two function above and create a function with three variables.

 function y = SimNAirplanes(b,a,x)

 y=[];

 k=0;

 for i=1:1:b

s=SimAirplane(a,x)

 if (s==1)

k=k+1;

 end

 end

 end

When using the third function, e.g. SimNAirplane(2,2,0.5) this is displayed:

s=0

 s=1

 s=0

My question is what command can I use, so that Matlab displays this: y=[0;1;0]?

you need to provide an indexing so

y(i)=SimAirplane(a,x);
