MATLAB: How to rotoate left and right

left rotate and right rotate

hai matlab users

can any say what is the matlab function or operator to rotate a 8 bit value.

for example i has a 8 bit binary value, i would like to rotate 3 time to its left

and later three times to its right.

example:

1010 0101

after three right rotation it will become 0010 1000 after three left rotation to the above number it will become 0000 0101.

i want just a << and >> equivalent in c language

can any one say how to do using this matlab function

Did you try bitshift()?

% Test example, 166 corresponds to your example of binary '10100110' 
M=[2 32 45;
   3 54 166;
   134 245 69]
rotfun = @(M,r) reshape(str2num(circshift(dec2bin(M,8),-r,2)),size(M))
rotfun(M,0)
rotfun(M,3)

Results:


ans =
          10      100000      101101
          11      110110    10100110
    10000110    11110101     1000101
ans =
       10000           1     1101001
       11000    10110001      110101
      110100    10101111      101010

MATLAB: How to rotate a line about center point?

Let's say you want to rotate around and arbitrary points designated by (ro,co);

Here how you can do it:

% Top left corner as center of rotation
ro=1;
co=1;
I=imread('peppers.png');
[r,c,nB]=size(I);
I2=zeros(2*r,2*c,nB,'like', I);
I2(r-ro+1:2*r-ro,c-co+1:2*c-co,:)=I;
Irotated=imrotate(I2,45);
