how to define a Three-dimensional symbol variable

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;

thank you

I didn't fully understand, you want to do one matrix? or several different matrices?

Answer 1

[ilona]

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

b(i,j,k) it's size like this

1,1

1,1,1,1

1,1,1,1,1,1,1,1

1,1,1,1,1,1,1,1,1,1,1,1,1,1,1

1,1

1,1,1,1

1,1,1,1,1,1,1,1

1,1,1,1,1,1,1,1,1,1,1,1,1,1,1

1,1

1,1,1,1

1,1,1,1,1,1,1,1

1,1,1,1,1,1,1,1,1,1,1,1,1,1,1
