How to find a substring in a cell array

Question

I am trying to use regexp in MATLAB to search for two words in strings in cell arrays. My cell array contains

strings={'1abc_2def_ghi_AB_12A','1abc_2def_ghi_BD_19A','1abc_2def_ghi_CD_16A',}

How would I go about constructing the expression to search the cell array for the string that contains both 'ghi' and '12'?

Thanks in advance for any assistance.

Where is your problem implementing this? Finding a matching regular expression or iterating the cell? — Daniel

How about this?

result = find(~cellfun(@isempty, regexp(strings, 'ghi')) & ...
    ~cellfun(@isempty, regexp(strings, 'AB')));

Or, using a single regular expression,

result = find(~cellfun(@isempty, regexp(strings, '(ghi.*AB|ghi.*AB)')));
