MATLAB: How to define a Three-dimensional symbol variable

Question

b(i,j,k);

i = 5,k = 3

for i = 1:5

     j = 2^i;

end

in other words,every row has different number of element for a centain k;

how to define these Three-dimensional symbol variable

thank you

Answer 1

do you mean something like that?

    % 

c = ones(1,3)
for ii=1:length(c)
CellArray{ii}=ones(ii,2.^ii)
end

or something like that:

    % 
c = ones(1,3)
k = 3
CellArray = {a b c}
for ii=1:length(c)
CellArray{ii}=ones(ii,2.^ii,k)
end
