- Is that [123; 456; 789], which is a 3-by-1 column vector of 3-digit numbers?
- Or do you mean {'123'; '456'; '789'} which is a 3-by-1 cell array of strings?
- Or do you want a 3-by-1 array of cells where each cell contains a 1-by-3 row vector of numbers, like {[1,2,3]; [4,5,6]; [7,8,9]}?
Matrix row cell concatenation

Hello,
I have a matrix and I would like to combine its row cells as an array of the matrix.
Ex:a
1 2 3
4 5 6
7 8 9
result:b
123
456
789
I tried a solution to from this link:
a = [ 8 1 6 ; 1 2 3 ; 4 5 6 ]
[l c ] = size (a) ;
b = cell (l,1);
for i =1 : l
b {i,: } = [ a(i,1) a(i,2) a(i,3) ] ;
end
but I get the out put as
ans =
[1x3 double]
[1x3 double]
[1x3 double]
any help would be appreciated. Thnx

b = reshape(arrayfun(@(x)polyval(a(x,:),10),...
1:size(a,1),'un',0),[],1);
Wanted = cell2mat(b)

What more do you need ? Doesn't the below give what you want??
>> a = [1 2 3
4 5 6
7 8 9 ];
>> bb=num2cell(string(a),1);
>> b=str2double(strcat(bb{:}))
b =
123
456
789
>> size(b)
ans =
3 1 % 3 by 1 vector
