MATLAB: My code for isn’t working. To store iterations from a FOR loop into a single variable as a single row vector

arrayarraysfor loop

Error: in an assignment A(I) = B, the number of elements in B and I must be the same.
X = 100;
b = zeros(1,9);
for a = 2:9;
y = dec2base(x,a);
b(a)= y;
end
display(b)

Hi Moses
1.
add ; after end
2.
MATLAB is case sensitive, X capital is not used and then dec2base expects undeclared x, just use one of them:
3.
b is attempting to collect variable length results from dec2base, a fixed length variable cannot be used unless it has room for all digits. zeros(1,9) only allocates 1 digit per b(a), yet b elements need have variable length
.
x = 100; 
b = {}; 
for a = 2:9; 
    b =[b; dec2base(x,a)]; 
%     b(a)= y; 
end
b = 
    '1100100'
    '10201'
    '1210'
    '400'
    '244'
    '202'
    '144'
    '121'
to read cell elements
     b{1}
     =
    1100100
    b{3}
    =
    1210
