converstion between two types

What is difference between

a=10101010

b= 1 0 1 0 1 0 1 0

when length(a) and length(b) both equal to 8 kindly tell me what is the difference between these two and is there any way to convert a into b or b into a?

Answer 1

[Azzi Abdelmalek]

a=123  % a is a number
b=num2str(a)  % b is a string
a=str2num(b)  % to get back a

For your case

c='0101'  % c is a string 
% If you want to get a vector [0 1 0 1] use

c-'0'

[Raza Ali]

its not working,

a=10101010 is not a number its binary value

[Azzi Abdelmalek]

a=10101010 % is not considered as a binary number by Matlab

If you want to represent a binary number, use a string

 a='10101010'

another way to represent a binary number is a vector

 a=[1 0 1 0 1 0 1 0]

Raza we went over all this already in your original question.

That's ambiguous code. The first line is okay - a is an integer with value 10,101,010 - but the second is not MATLAB code. You can do

whos a
class(a)

to learn a lot about the variables.
