WebDescription. C = bitshift (A, k) returns the value of A shifted by k bits. Input argument A must be an unsigned integer or an array of unsigned integers. Shifting by k is the same as multiplication by 2^ k. Negative values of k are allowed and this corresponds to shifting to the right, or dividing by 2^ abs ( k) and truncating to an integer.

WebBecause bit-wise logical operations compare corresponding bits in two numbers, it is useful to be able to move the bits around to change which bits are compared. You can use bitshift to perform this operation: bitshift (A,N) shifts the bits of A to the left by N digits. This is equivalent to multiplying A by 2 N.
