WebAug 11, 2024 · The diference is that the MATLAB version can work on arrays, but you can just loop in the C++ code. Maybe Eigen has similar functionality to compute these operations on whole arrays, but even if it does not have that, it probably has a way to access the memory where the array elements are stored. http://www.ece.northwestern.edu/support/local-apps/matlabhelp/techdoc/ref/bitshift.html

Bit-wise operations can have surprising applications. For example, consider the 8-bit binary representation of the number : 00001000. 8 is a power of 2, so its binary representation contains a single 1. Now consider the number : 00000111.
