Change Bit Value for Some positions

In binary number. Example 8 bit resolution in the measurement 10001111. In case I have many measurement data with 8 bits. And I want to change the bit value in the 4th bit only. If it is 0 then changes to 1, if it 1 then changes to 0.

so values 11101001 will become 11111001 and value 11100000 will become 11110000

I have a lof data, I can do changes in the 8th bits using command DEC2BIN(BIN2DEC(F4)+DEC2BIN(1)). I am still looking for the other positions.

Kind regards

Use the 'xor' function. If one of the arguments is of type uint8 with a single bit equal to 1 and the rest 0, the corresponding bit in the other uint8 argument will be reversed.

xor(11110000,00010000)

ans =

     0

I want the ans 11100000

My apologies! I should have said, "Use the bitxor function." (The 'xor' function handles logical trues and falses in a manner similar to & and | operations.) The 'bitxor' function deals with the individual bits in a number. However, writing bitxor(11110000,00010000) will undoubtedly interpret those as decimal, not binary, numbers.

Confession: At the moment I forget how one would enter binary numbers. In your example (out of desperation) I would write bitxor(15*16,16) where 15*16 in binary is 11110000 and 16 in binary is 00010000, which should give as a result 224, which has one bit reversed - that is, decimal 224 = binary 11100000.
