Hello,
How to replace the empty cells " [ ] " in the attached matrix to a 4-bits string we can convert the whole array matrix to double.
For example,
if we have thw following row:
[ '0001', '0101' , '1010', [ ], [ ], [ ], '1111']
it becomes:
[0,0,0,1,0,1,0,1,1,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,1,1,1,1]

How about the following?
load('Key.mat');
idx = cellfun(@isempty,Key); % Find the indexes of empty cell
Key(idx) = {'0000'}; % Replace the empty cells with '0000'

load('Key.mat');
Key1 = Key(:);
Key1 = reshape(replace(string(char(Key1{:}))," ","0000"),size(Key,1),size(Key,2));
results in a string array filing up all empty elements with "0000".
