x=repmat([1 2 3 4],4,1); x(6,6)=0
x = 6×6
     1     2     3     4     0     0
     1     2     3     4     0     0
     1     2     3     4     0     0
     1     2     3     4     0     0
     0     0     0     0     0     0
     0     0     0     0     0     0
perm=[1,2,5,6,3,4];
x(perm,perm),
ans = 6×6
     1     2     0     0     3     4
     1     2     0     0     3     4
     0     0     0     0     0     0
     0     0     0     0     0     0
     1     2     0     0     3     4
     1     2     0     0     3     4

MATLAB: How to permute rows with specific number of permutation

Hi Sadiq,

In the row shift, the function handle csm takes in first input as row and next input as image I, but while accessing it in the function handle callcsm, you are sending first image I and then column indexes. Make the update here as stated and it will solve the issue.

csm = @(row,I) circshift(I(row,:),[1-row,3]);    % Arbitrary Matrix
callcsm = @(I) csm(1:size(I,1),I); % Make the call to csm with proper signature as defined in csm

Hope this helps.

Regards,

Sriram

MATLAB: Time shifting

Omit the square brackets around the case blocks and close the SWITCH and IF blocks with an END.

switch(s)
case 1
   for i=1+n:1:21+n
     if(x(i)>0)
       y(i)=1;
     else
       y(i)=0;
     end
   end
case 2
   for i=1-n:1:21-n
     if(x(i)>0)
       y(i)=1;
     else
       y(i)=0;
     end
   end
end
