I want to compare two arrays each containing 6 numbers e.g. [1,2,3,4,5,6] and [4,8,6,10,11,12]. I want to determine how many numbers are common to both arrays (not necessarily in the same location) so the above would yield an answer of 2 as 4 and 6 are common to both. Thanks!

See:
doc ismember
With code:
a = [1,2,3,4,5,6]
b = [4,8,6,10,11,12]
nCommon = sum(ismember(a, b))
Maybe the inputs are not unique, then apply unique() at first.
