Fundamentals of MATLAB shift operation

bitshift It's moving Bit operation , It is a cut-off operation . The syntax is bitshift(a,b)

among a Is the shifted number ,b Is the number of bits moved .a It can only be a positive number .b It's a positive number , Shift left .b When it's a negative number , Shift right .

Such as bitshift(5,1), Namely the 5 Moving to the left 1bit.

annotation ：5 Binary system yes 0101, Move one bit to the left , become 1010（ Binary system ）=10（ Decimal system ）

bitshift(5,1)

ans =

    10

Moves to the right one become 0010 = 2 （ Decimal system ）

>> bitshift(5,-1)

ans =

     2
