Error using arrayfun All of the input arguments must be of the same size and shape

I am trying to convert to binary numbers in a string with this code:

sbox=[12;5;6;11;9;0;10;13;3;14;15;8;4;7;1;2];
f=@(x) dec2bin(x,4);
l=arrayfun(f,sbox,'UniformOutpot',false);

But i get the following error

Error using arrayfun
All of the input arguments must be of the same size and shape.
Previous inputs had size 16 in dimension 1. Input #3 has size 1

Error in nl (line 3)
l=arrayfun(f,sbox,'UniformOutpot',false);

I also tried to input sbox=[1,1,1] but it gives me the same error

Answer 1

[Fangjun Jiang]

no need to use arrayfun() for this.

cellstr(dec2bin(sbox,4))

Answer 2

Change 'UniformOutpot' to 'UniformOutput' so that MATLAB doesn't think it's another input variable for f.
