I'm certain that there is a way for me to vectorize this loop but I can't see it
TestRan is a 170x1 double
CorrectVector is a 90x1 double, a subset of TestRan
I need to populate a 170x1 double CorrectLogical with 0/1 based on CorrectVector
what I have:
CorrectLogical = zeros(length(TestRan,1))
for i=1:length(CorrectVector)
CorrectLogical(TestRan==CorrectVector(i)) = 1
end

CorrectLogical = zeros(size(TestRan))
CorrectLogical(ismember(TestRan,CorrectVector))=1

CorrectLogical = ismember(TestRan, CorrectVector)
