cell arrray that stores with every iteration a new set of values

Here,I have a pre-defined function called intersections(x,....) that finds the intersections between 2 functions of x and stores the (x,y1) and (x,y2) values directly into the output cell/array.Now,for each iteration of the loop,I get a set of (x,y1) and (x,y2) values. I want to store them in an array without losing the previous iteration's values. So,I figured I'd use a cell array except I can't decipher its working mechanism.Someone,please help me with this. Have a look at the code below.[I pasted the whole code at the end].

for i=1:5

for j=1:5

%functions f1 and f2

y1=@(x)C.*(x)./((x.^p)+1);

y2=@(x)(r.*(1-(x./q)));

[a{i,j},b{i,j}] = intersections(x,y1(x),x,y2(x),1);

%a line of plot commands follow[not important] end

end

I initially used [xout,yout]= intersections(x,y1(x),x,y2(x),1); to store the coordinates of the intersections but it kept getting erased out after each iteration.I want the whole data stored coordinates stored in 1 cell array.

I do not understand the question. What is erased? Why is y1 and y2 redefined in each iteration? Why is intersections called with the same inputs in each iteration?

clear
y1=@(x)C.*(x)./((x.^p)+1);
y2=@(x)(r.*(1-(x./q)));
for ii=1:5
 for jj=1:5
   [aa,bb]= intersections(x,y1(x),x,y2(x),1);
   a{ii,jj}=aa
   b{ii,jj}=bb
 end
end
