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.

WebJun 16, 2006 · matlab shift left. Hi, I copy the x >> y definition from a video standard (H.264). Arithmetic right shift of a two's complement integer representation of x by y binary digits. This function is defined only for positive integer values of y. Bits shifted into the MSBs as a result of the right shift have a value equal to the MSB of x prior to the ... WebApr 11, 2013 · More Answers (1) Walter Roberson on 11 Apr 2013. 1. Link. MATLAB does not offer that operation directly. You can extract the bits that would be shifted "off the bottom", do the shift, and then put the bits back on top. Or you can proceed numerically, such as. mod (x,2)*2^7 + floor (x/2)
Web2) I then devised a more optimal solution, though not a one line code it is optimised for speed: reverse = uint16 (0); for i=1:16 reverse = bitor (bitshift (reverse,1), uint16 (bitand (forward,1))); forward = bitshift (forward,-1); end. Using the same CRC code, but with this used instead of (1), it took a little over 500 seconds to complete, so ...
