Hi,
Say your input matrix(t) is an n*m matrix.
for i = 1:n
for j = 1:m
s = t(i,j);
t(i,j) = t(i,j+1);
t(i,j+1) = s;
end
end
The above code will shift the first element of each row to the last.
The same can be performed without a loop.
s = t(:,1);
t(:,1) = [];
t(:,n) = s;
I hope it was helpful
Regards
