any easier way to find cell by string

Hi:

I have a cell array like below:

    A{1}='test1a';
    A{2}='test2a';
    A{3}='test3a'; 
    A{4}='test4a';
    A{5}='test1b';
    A{6}='test2b';
    A{7}='test3b'; 
    A{8}='test4b';
...

I want to find the location where 'test*a' are at, in this case, it should be 1,2,3,4

Yes, I can write a for-loop to read-justify cell in this array one by one, but I want know if there is any easier way to do this? such as

strfind(A,'test*a')

of course this is not available in Matlab

Thanks!

Assuming the strings all start with 'test', e.g.

find(cellfun(@(C)C(end)=='a',A))

Sorry I do not state the problem clearly, the start is not determined

However, I think your answer provide a solution.... I can operate with your answer twice and then solution is found:

a=find(cellfun(@(C)C(end)=='a',A));
b=find(cellfun(@(C)C(end)=='test',A));
intersect(a,b)

Thanks!

Well, I think you would need to do something like this instead:

find(cellfun(@(C)numel(C)>4 && strcmp(C(1:4),'test') && C(end)=='a',A))

But really what is needed is an Answer from someone who knows regexp( ) well (and that isn't me).
