Hi,
I wonder how to make invert bit vector ?
*For example:*
I have A vector: A=[0 1 0 1 0 1 0 1 0 1 0 1 1 0 1 0] that mean 2 couples LSB are 1 0 1 0 and the rest are 01 0 1 0 1 0 1 0 1 0 1
And I want to invert it to B=[1 0 1 0 0 1 0 1 0 1 0 1 0 1 0 1] the result of the inverted vector should be MSB 1 0 1 0 and the rest couple bits 0 1 0 1 0 1 0 1 0 1 0 1.
Anyone knows how to do it ?
Thanks,
Henry

Hi,
Vactor A changing all the time (depends on an input that runs from 0 to 10 for example. for example:
in=0 then A = [0 1 0 1 0 1....0 1 0 1]
in=1 then A = [0 1 0 1 0 1....0 1 1 0]
in=2 then A = [0 1 0 1 0 1....1 0 1 0]
...
in=9 then A = [0 1 1 0 1 0....1 0]
in=10 then A = [1 0 1 0 1 0....1 0]
the resolt should be:
A (when in=0) then B = [0 1 0 1 0 1....0 1 0 1]
A (when in=1) then B = [1 0 0 1 0 1....0 1 0 1]
A (when in=2) then B = [1 0 1 0 0 1....1 0 1 0]
and so on...
Can you know how to do it ?
Thanks, Henry

@Henry Buck: today I formatted your code correctly for you, but in future you can do it yourself. It is pretty easy: select the code text and click on the {} Code button that you will find above the textbox.
It must be a slow day for, but your three examples do not clarify the pattern for me. Please provide some more complete examples. Simplifying the examples does not help either, because then I have to make up something to test my code with, and there is no guarantee that I will make up the same vectors as you have. So if you want a solution to work for your example then you need to provide them to us.

function gate_h = gate_array_h6(I_H, indx_h)
no_cells = 20; gate_h = zeros(1, no_cells * 2); gate_h(1:2:indx_h*2) = 0; gate_h(indx_h*2+1:2:no_cells*2-1) = 0;
if I_H > 0 gate_h(2:2:(no_cells-indx_h)*2) = 1; gate_h((no_cells-indx_h)*2+1:2:no_cells*2-1) = 1; else gate_h(1:2:indx_h*2-1) = 1; gate_h((indx_h+1)*2:2:no_cells*2) = 1; end
This code craete gate_h vector according to I_H and indx_h(goes from 0 to 20). the result of gate_h(depending on the inputs) is 40 bits: indx = 0 then gate_h = [0 1 0 1..... 0 1 0 1 0 1] indx = 1 then gate_h = [0 1 0 1..... 0 1 0 1 1 0] indx = 2 then gate_h = [0 1 0 1..... 0 1 1 0 1 0] and so on....till indx = 20: indx = 20 then gate_h = [ 1 0 1 0 1 0.... 1 0 1 0].
The code above works perfect.
  • On the same function I want to built new function gate_l.the result should be:*indx = 0 then gate_l = [0 1 0 1..... 0 1 0 1 0 1]indx = 1 then gate_l = [ 1 0 0 1..... 0 1 0 1 0 1]indx = 2 then gate_l = [ 1 0 1 0..... 0 1 0 1 0 1]indx = 2 then gate_l = [ 1 0 1 0 1 0..... 0 1 0 1]and so on....
I hope it is much more clarify. Thank you for your answer.
