Hi
could anyone please help me? I want to define A as a integer number:101011, but next i need to treat with this number as a binary format! for example i want get not from it! imagine i have D=[1 1 1 0 1 0 0 1 1 0 1] an i extract A=D(7:11)=01101 and want to get A_not=10010 but because of the integer nature of D, i can not do this! how can i do?

it is string i have a mistake in this explanation assume with some instructions i got a single number:01101 from vector D=[1 1 1 0 1 0 0 1 1 0 1]
now i want to get not from it!
let me explain it with details: i have a vector of integer number(but this vector consist just 0 and 1):D=[1 1 1 0 1 0 0 1 1 0 1]
i want to extract some elements of it as a single number: A=D(7:11)=...=01101
lots of instructions exist to get a single number as A=D(7:11)=...=1101
for example:
x = [0 0 1 0 1 0 1];
p = flipud([1; cumprod(repmat(10, size(x, 2) - 1, 1))]);
y = x * p;
this instruction results a single integer number as:
y=10101
but i want to get 0010101 and i can get 1101010(as a single integer number) with do little changes in this instructions i think if i can get not of this result so i have 0010101 but because it is integer, "not" of this, is "0"!!
so i want to get 0010101 (as a binary single number albeit if i get exactly a single number 0010101 it is not important that it is binary or integer because i want to compare it with a constant that can define it binary or integer, but i think it is impossible that i get 0010101 as integer!!)

You cannot get leading zeros unless y is a string. It can't be a logical data type, integer data type, or double data type and have leading zeros unless you use fprintf() or sprintf() to display it as a string.

You can use the logical() function.
D = [1 1 1 0 1 0 0 1 1 0 1]
A = logical(D(7:11))
A_not = ~A
