How to concatenate each row of a matrix into a vector ?

Hey there,

I have a matrix 1000x7 of double (only 0 and 1) like that :

0     0     1     1     0     0     0
0     0     1     1     0     0     0
1     0     1     1     0     0     0
...
0     0     1     1     0     0     0
0     0     1     1     0     0     1
0     0     1     0     0     0     0

For each row, I have to concatenate each column value to get a vector of strings like this

0011000
0011000
1011000
...
0011000
0011001
0010000

Do you have any idea of how could I do that ?

% create fake data
A = [0     0     1     1     0     0     0
0     0     1     1     0     0     1
0     0     1     0     0     0     0]; 


% Convert to char array
s = arrayfun(@(x)sprintf('%d',x), A)
% s =
%   3×7 char array
%     '0011000'
%     '0011001'
%     '0010000'

% if desired, convert to cell array of strings
c = cellstr(s)
% c =
%   3×1 cell array
%     {'0011000'}
%     {'0011001'}
%     {'0010000'}

Thanks a lot !

Is there anyway to say that one row like '0011000' is a binary string ?

[Adam Danz]

If you're acting on the cell array stored in 'c', the line below will produce a logical vector where 1s indicate rows that are binary (ie, composed of 1s and 0s). It does this by removing any 1s or 0s from each string and determining if that results in an empty string.

isBinary = cellfun(@(x)isempty(erase(x,{'0','1'})), c)

result = char(A+'0');
