loop on a strfind

Hi all, I have a loop as such:

parfor i =1:1000000

    ZZ= strfind(A2,lm(i,:));

end

now this lm is fine it's a set of strings of size 10 (many of them). And A2 is a large string.

I need to modify this...I have another string B2.

I need to do it so that at the first iteration the strfind looks in A2, then in the second iteration (i=2) then it looks in [A2 B2(1)], then on third iteration it looks in [A2 B2(2)] etc....

If anybody needs clarification I will rewrite question. Thank you.

I think this can be done with arrayfun.

% Your inputs
A2 = 'Number'; 
B2 = '0123456789';
lm = char(randi([32 64],10,100));

% Make the thing strings you want to find
ABz = strcat(A2,B2(:));

% Find them
out = arrayfun(@(ind) strfind(ABz{ind,:},lm(ind2,:)).1:length(ABz),'uni',false);
