Say I have a cell array:

cell_array={'AA','KK','AKs','QQ','AKo'}:

How do I attach the different suits (i.e. heart, club, spade, and diamond) into the string? (I would like to expand the given combinations with their respective suits).

Example:

for pair AA: AhAc, AhAs, AhAd, AcAs, AcAd, AsAd

and for suited nonpair AKs: AhKh, AcKc, AsKs, AdKd

and so forth for the remaining pairs, suited nonpairs and offsuit nonpairs.

It seems that 'str', 'strrep', etc. can only append a character in the end of a string - I would like to insert a character (h,c,s,d) in between as shown above.

well, appending a single character to another string is simple: str1 = ['AA', 's']

to insert characters in the middle of the string, i would first concatenate the strings and then change the order of the characters. for example:

str1 = ['AA' , 'hc'];
str1 = str1([1, 3, 2, 4])

Thank you very much!

Say I get a resulting array:

cell_array={'AX','BY'};

It is easy to manipulate the strings 'AX' and 'BY' (to isolate, sort, identify etc.), but I cannot seem to find an approach to "look" into the individual components of 'AX' or 'BY'. I would like to make a loop in which I only consider 'AX' and not 'BY'. Specifically, I would like to consider the case with 'A' (and not 'AX' while keeping 'AX' intact for subsequent analyses, i.e. not remove the 'X')

Should I maybe post a new thread?
