What function in MATLAB gives the log, with base 2?
LOG2 Base 2 logarithm and dissect floating point number.
Y = LOG2(X) is the base 2 logarithm of the elements of X.
[F,E] = LOG2(X) for each element of the real array X, returns an
array F of real numbers, usually in the range 0.5 <= abs(F) < 1,
and an array E of integers, so that X = F .* 2.^E. Any zeros in X
produce F = 0 and E = 0. This corresponds to the ANSI C function
frexp() and the IEEE floating point standard function logb().
See also LOG, LOG10, POW2, NEXTPOW2, REALMAX, REALMIN.

So what line of code would add 1 to x, and then take the log, base 2?
