Hi Everyone,

I have one excel file, which has binary data and when i extract this data in matlab i get this as string i.e.

k='00101101011010101101101111101110111100000001010000110010011000101111000101001010';

now i want to convert it into

k=[0, 0, 1, 0, 1, 1, 0, 1, 0, 1, 1, 1, 1, 1, 1, 0, 1, 1, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 1, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 1, 1, 1, 1, 0, 1, 1, 0, 1, 1, 1, 0, 0, 0, 1, 1, 0];

So that the values remain the same but i can convert it into a double like i mentioned above. Your help will be highly appretiated

How about something like this?

k='00101101011010101101101111101110111100000001010000110010011000101111000101001010'
k = '00101101011010101101101111101110111100000001010000110010011000101111000101001010'
str2double(num2cell(k))
ans = 1×80
     0     0     1     0     1     1     0     1     0     1     1     0     1     0     1     0     1     1     0     1     1     0     1     1     1     1     1     0     1     1
