Get the index for the search of multiple strings within an array of strings

Hi,

I have a (1x128) cell array like this: "list" = 'S01R' 'S02R' 'S03R'... etc And another short (1x16) cell array with the same type of characters, eg, "bad" = 'S01R' 'S02R' 'S03R'... etc

I want to know the index of my "list" where I may found the items listed in "bad", I'v tried regexp but this function only allow me to find single strings in my list, Also, I don't know how to get the index in a orderer list instead of a cell array like this c=[] [] [] [1] [] [] [] [] []

Thanks for any idea,

JL

Please post examples in valid Matlab code, such that they can be used directly in an answer by copy&paste.

See FEX: CStrAinBP: Reply the indices of common strings.

Is this what you were looking for?

   list = {'bad','worse','good','okay'};
   badlist = {'bad','worse'};
   idx = ismember(list,badlist);

This returns:

   idx = 1 1 0 0;

This works for exact text search, but not for if a string contains a particular set of characters. I find strfind() a better approach if you have that particular use case.

did you try "intersect" ???

[C,ia,ib] = intersect(A,B) example

thx for suggesting interstect for strings

Thanks to all for your answers, I found something that works, http://www.mathworks.com/matlabcentral/newsreader/view_thread/310652#846320

CStrAinBP it does make it too,
