Why creating cell then it become table.

Hi,

I have a main n a function. This is the main:

k=3;
data=[2,1;2,4;5,3;3,3;4,3;1,3;1,1;1,2;4,2;5,2];
noofrow=10;
pm=[4.46548518703744e-13,0.999999999972956,2.65973210752259e-11;0.999999999721704,2.76819651086087e-10,1.47632293709860e-12;0.999999905913871,9.40858876460889e-08,2.41912087988739e-13;1.30415928862666e-20,3.82843279259685e-16,1.00000000000000;1.50904190683861e-09,2.27976771986804e-08,0.999999975693281;1.48213530202206e-09,0.0160961639229467,0.983903834594918;1.95427183156120e-14,4.26017383695369e-12,0.999999999995720;0.999999999993147,6.85195488054645e-12,1.12188335455077e-15;0.999999999999519,4.77821392183546e-13,3.10108174121301e-15;1.13939214498226e-07,0.999999885823348,2.37437863835418e-10];
display_centroid(pm,k,data,noofrow)

This is the function:

function[]= display_centroid(pm,k,data,noofrow)

transpose_pm=pm.'

maxU = max(transpose_pm)
index = cell(k,1)

for i=1:k
    index{i}= find(transpose_pm(i,:) == maxU)
end

disp(index)

I had created the index as cell. While looping the index still in cell. However when the end of loop. The cell become table as below:

    {1×4 double}
    {1×2 double}
    {1×4 double}

    [1×4 double]
    [1×2 double]
    [1×4 double]
   

i need it to be maintain as cell as needed in my further coding. Please help me to understand this and also how i want to be the index in cell. TQIA

I do not see any table. Which MATLAB release are you using?

k=3;
data=[2,1;2,4;5,3;3,3;4,3;1,3;1,1;1,2;4,2;5,2];
noofrow=10;

display_centroid(pm,k,data,noofrow)

index = 3×1 cell array
    {0×0 double}
    {0×0 double}
    {0×0 double}

    {[2 3 8 9]}
    {[   1 10]}
    {[4 5 6 7]}

function[]= display_centroid(pm,k,data,noofrow)
    
    transpose_pm=pm.';
    
    maxU = max(transpose_pm);
    index = cell(k,1)
    
    for i=1:k
        index{i}= find(transpose_pm(i,:) == maxU);
    end
    
    disp(index)
end
