How do perform negation on binary values using matlab?

for example given input is = 10011011 i need negation of only MSB bit therefore the result should be =00011011 how can this be performed using MATLAB

[the cyclist]

What is the variable type? Is it a character string?

Is this any different than your prior post http://www.mathworks.com/matlabcentral/answers/116422-how-to-perform-cancatenation-of-binary-numbers-using-matlab?

[yeshwini]

yes sir, one was binary cancatenation and the other is negation of bit here input is binary means bits

Here is one way, if the input is a character string:

char(num2str(x'=='0'))'

I feel that there must be a better way, and I am just being dumb.

god-tier solution. thanks king.

Answer 2

char('a'-x);

where x is your input string.

The synergy was quite deliberate on my part. If you would like to enter this as a solution yourself, I will happily delete this one, to give you the credit.

I realised that it was deliberate - and effective! I put a solution on Cody, no need to change anything.

char('a'-x); helo sir,what is 'a' here

[the cyclist]

'a' is the character string for the letter 'a'. This is a nice trick to "subtract" your string x from the ASCII character 'a', which gives you what you want.

So, if

x = '0110';
y = char('a'-x);

will result in y having the value '1001'.
