How to save the result of each loop separately

I want to create two variables which are matrices is zeros(3,2) and zeros(4,2)

y = [3 4];
for i=1:length(y)
    x=zeros(y(i),2)
end

x = 3×2

0 0 0 0 0 0

x = 4×2

0 0 0 0 0 0 0 0

I dont want the second loop to overwrite the result of the first loop.

One option is to use a cell array to store dissimilar objects

y = [3 4];
for i=1:length(y)
    x{i}=zeros(y(i),2)
end

x = 1×1 cell array
    {3×2 double}

x = 1×2 cell array
    {3×2 double}    {4×2 double}

Though not shown here, x can be preallocated based on the number of elements in y.

Perhaps this (using a cell array)?

y = [3 4];
for i = 1:length(y)
    x{i} = zeros(y(i), 2)
end

x = 1×1 cell array
    {3×2 double}

x = 1×2 cell array
    {3×2 double}    {4×2 double}

hello

some solutions :

y = [3 4];
for k=1:length(y)
    % solution 1 : store as cell array
    x{k} =zeros(y(k),2);
    % solution 2A : store as structure
    s(k).data =zeros(y(k),2);
    % solution 2B : another structure
    t.data{k} =zeros(y(k),2);
end
x

x = 1×2 cell array
    {3×2 double}    {4×2 double}

s

s = 1×2 struct array with fields:
    data

t

t = struct with fields:
    data: {[3×2 double]  [4×2 double]}
