MATLAB - Convert Number Character array to Number Integer array/matrix?

*My problem*: Hi, I have an array *A of type char*, that reads like this:
196800271010
902589451069
052068830384
901778191098
I want to turn A into a numerical matrix that will separate the characters into individual number integers like so
[1 9 6 8 0 0 2 7 1 0 1 0
9 0 2 5 8 9 4 5 1 0 6 9
0 5 2 0 6 8 8 3 0 3 8 4
9 0 1 7 7 8 1 9 1 0 9 8]
What is the best way for this? *I've tried* str2num(A), but that treats the characters as one whole number per line (Ie first line is 1.9680) I've also tried this for loop
for i = 1:5 %the number of rows in the char array
s = num2str(A(i,:));
for t = length(s):-1:1
result(t) = str2num(s(t));
end
But this just returns the last line of the array, I want to have all of them. Thanks.

your code is correct, just one thing you are need to look is that you need to store all the element in the array,
for i = 1:5
s = num2str(A(i,:));
for t = length(s):-1:1
result(i,t) = str2num(s(t));
try this you will get your result

Needs a couple of end statements.
What is the purpose of the num2str(A(i,:)) step when A is already a character array? num2str() applied to a character vector returns the same vector?
