How to store values from a loop?

I have a .m function file of Y(x,y), and the fzero command below to find the zero for varying values of y:

if true
for y= 2:0.1:10
 x = fzero(@(m) Y(m,y),4);
end
end

however after each loop, the previous value is overwritten, is there a way I can save them all?

Kind Regards,

John.

Store them in a vector using an index like in the following:

y = 2:0.1:10;

% For all elements in vector y
for i=1:numel(y)
  % Set ith element of vector x
  x(i) = fzero(@(m) Y(m,y(i)),4);
end

ii= 2:0.1:10
sol=cell(numel(ii),1)
for y=ii
 x = fzero(@(m) Y(m,y),4);
 sol{y}=x;
end
celldisp(sol)

how to save celldisp(sol) to file.mat?

There are two ways to do this, the following is the less efficient way

x=[];
if true
for y=2:0.1:10
x=[x; fzero(@(m) Y(m,y),4)];
end
end

Basically, the above code will store all the values in each loop in a matrix x. You can also preallocate and create a matrix by using x(i)=rest of it

i=1
for loop
x(i)=
i=i+1;
end
