when i run the command

B = arrayfun(@(N) randi(2,N), repelem((1:3).',5), 'uniform', 0)

i am getting B = 15×1 cell array

{[ 1]}

{[ 2]}

{2×2 double}

{3×3 double}

{3×3 double} and the data inside are

3

[1,1;1,1]
[1,1;2,1]
[1,3;3,1]
[3,1;1,3]
[1,1;1,1]
[1,1,3;1,2,2;1,2,1]
[3,2,2;3,1,3;1,2,3]
[1,2,2;1,3,1;1,2,3]
[3,1,1;3,3,1;3,2,3]
[3,2,1;3,1,1;3,2,1]

but I actually need B =

15×1 cell array

{1×1double}

{1×1 double}

{1×2 double}

{1×3 double}

{1×3 double} containing the following values

If i run the above the command it generates 15x1 cell array. thanks for it.

But i need to have for row having 1x1 double the value should be of 1 and not more than 1 and for 1x2 the value should be of [1,2 ], [1,1], [2,1] and not more than 2, [2,2]...

for 1x3 double the value should be [1,2,3], [3,2,1], [1, 2,2] and not more than 3 and should ignore [1,3,3] as it leaves 2.

Could you please help me to write how should I need to cell array in the above mentioned manner.

You have a fixed outcome, and you have no explainable reason for that particular outcome. You should just write static assignment statements.

Remember the fundamental rule of practical programming: get it working first, and worry about making it shorter or faster later. You have been held up for days trying to write these things in a compact way, when you could have just written something that got the required outcome and moved on to the next step.
