I have a character A. I converted this into a binary form(say B). I need to perform some operations using B. While doing this I need to check whether the element B(1)=1 or 0.
For doing so, I write
if B(1)==1
But it doesn't work. It works when I written like this-
if B(1)=='1'
What is the reason? Please tell me...

Apparently B is still a character array. Would help if you said how you converted it. Type whos B to see the type.

I do not understand, what the "binary form" of a character is. Please post the corresponding Matlab code to clear the details.

You are comparing the char '1' with the numeric 1.
>> double('1')
ans =
49
as in the ASCII table.
You have to rescale '1' to 1:
'1'-'0' == 1
and in your case
B(1)-'0' == 1
