I am trying to create a logical array in a loop, wherein each iteration of the loop should create a new column in my array:

for i= 1:size(Behaviours) %Behaviours is a 27x1 cell array containing strings
        temp = strcmp(Shank2_KOs(k).BehaviourType, Behaviours(i)); %creates the logical vectors
        temp_array = temp(:,i);
    end

You are overwriting both variables every iteration. What do you want to store in which variable?

I would like to store the colum vector output of "temp" as a new column in "temp_array".

In a loop the indexing works just as normal. I also made some other changes to your code.

temp_array=zeros(____,numel(Behaviours));
for n= 1:numel(Behaviours) %Behaviours is a 27x1 cell array containing strings
    temp = strcmp(Shank2_KOs(k).BehaviourType, Behaviours(n)); %creates the logical vectors
    temp_array(:,n) = temp;
end
