Can you give a short example of how you are getting a longer decimal string from the shorter binary string, like '1101001' goes to '123456787654627838' or something?

If we have k='0000000100000010' then there is a need to get (say)h='1 2'
that is for first 8 bits...'00000001==> 1' for next 8 bits... '00000010==>2'

bin2dec probably does most of what you want:
>> bin2dec(reshape('0000000100000010',8,[]).')
ans =
1

You seem to have put my code inside a loop, and then inside that loop you access one character of the string at a time, like this:
k(i)
What do you expect to do with one character at a time?
My answer works perfectly for a string with size 1*524288, and it does not need any loops:
>> str = char(randi(48:49,1,524288));
>> vec = bin2dec(reshape(str,8,[]).')
vec =
233
164
146
110
134
162
238
203
etc
