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.

In C, bitwise shift can be done using '<<, >>, which are even combined with assignment operators into '<<=, >>=. In Matlab, I found functions like bitshift, bitsll, bitsra, bitsrl. Which are far less convenient than '<< >> operators. Is there any better way to do shifting.
