Dear Mai adel Mohamed ,

Welcome!

You can follow the instructions in the link:https://www.mathworks.com/matlabcentral/answers/247874-how-to-select-specific-elements-in-a-matrix

You can select the the data in the position you intend and then after that you can append the selected array to the original one!

Best wishes

You may try the following

for I = 1: 8:512

x(end +1) = x(I)

end

but in this case the vector will not be of fixed size. It keeps updating.

Hopefully this will help you.

Regards

Saleh Albashrawi

thanks for your reply, but i need it to be fixed 512 , can you help me

Thanks Dr for your reply . i mean i need to do like this example

if v= [ 1 2 3 4 5 6 7 8 9 10] and lets say i will move every 2 bits so i need to have this at the end

x= [ 2 4 6 810 1 3 5 7 9]
