How can I make a string?

I have some values as : A=

0

0

1

0

1

0

1

0

0

1

1

0

I want to take every 4 values in a string.

Output should be : B =

0 0 1 0

1 0 1 0

0 1 1 0

And, after that I want to covert the values from binary to decimal.

Final output should be :

2

10

6

It cuould be better for me if it is done in a loop. Because, I have a length of "A" near 40+ lacs.

 B=reshape(A,[4,3])';
 C=num2str(B);
 bin2dec(C)

Output :

 ans =
     2
    10
     6

Note: Loop is not necessity .

You used B=reshape(A,[4,3])'; where 3 is for length.

What can I use if the length is unidentified.? (Length can be anything anytime)

Should I then use this code..?

K = length(A);

B=reshape(A,[4,K])';

"Should I then use this code..? K = length(A); B=reshape(A,[4,K])';"

No, because the reshaped vector would have to have K/4 columns, not K columns.

But in any case, experienced MATLAB users would recommend this syntax:

B = reshape(A,4,[]).';

and simply letting reshape calculate how many columns are required.
