How can I create a matrix with matrix elements of different datatypes?

I want to make a nx2 matrix in which the first column consists of integers but the second column consists of a structure. Something like this,

Please let me know how to create this matix. Thanks in advance!

You can use a cell array to mix datatypes:

n=5;
mat = cell(n,2);
for i = 1:n
    mat{i,1} = i;
    mat{i,2} = -i:i;
end
mat

mat = 5×2 cell array
    {[1]}    {[                    -1 0 1]}
    {[2]}    {[               -2 -1 0 1 2]}
    {[3]}    {[          -3 -2 -1 0 1 2 3]}
    {[4]}    {[     -4 -3 -2 -1 0 1 2 3 4]}
    {[5]}    {[-5 -4 -3 -2 -1 0 1 2 3 4 5]}
