I want cell a and b merged together.
1) When one of the two string as a value (as 5,6 or 7) I want c to have that value.
2) When the two cells has both the letter A and B, I want array c to have the letter A.
3) When the cells string has the letter A , I want array c to have the letter A.
4) When the cells string has the letter B , I want array c to have the letter B.
%Given cells
a={'A'; 'B' ; 5 ; 6; 'A' ; 'A'; 'B'};
b={ 7; 'B' ;'A' ;'B'; 'A' ; 'B' ; 'A'};
%Wanted Outcome
c={ 7; 'B' ; 5 ; 6; 'A' ; 'A'; ; 'A'};

Sorry the c had a typo. Here is the good one.
c={ 7; 'B' ; 5 ; 6; 'A' ; 'A'; 'A'};
No this is not a homework question. It is simplified version of a piece of script I'm working on.

@Jan I am think now on something like this.
a={'A'; 'B' ; 5 ; 6; 'A' ; 'A'; 'B'};
b={ 7; 'B' ;'A' ;'B'; 'A' ; 'B' ; 'A'}
c=cell(7,1);
for s=1:7
if a(s,1)=='A' && a(s,2)=='A'
c(s)='A'
elseif b(s,1)=='B' && b(s,2)=='B'
c(s)='B'
elseif b(s,1)=='A' && b(s,2)=='B'
c(s)='A'
elseif b(s,1)=='B' && b(s,2)=='A'
c(s)='A'
else
c(s) = %value
end
end

a = {'A'; 'B' ; 5 ; 6; 'A' ; 'A'; 'B'};
b = { 7; 'B' ;'A' ;'B'; 'A' ; 'B' ; 'A'};
c = cell(size(a)); % Pre-allocation
isNum_a = cellfun('isclass', a, 'double');
isNum_b = cellfun('isclass', b, 'double');
sameChar = strcmp(a, b); % replies FALSE, if one is a number
c(isNum_a) = a(isNum_a);
c(isNum_b) = b(isNum_b); % prefer b if both are numbers [EDITED, Typo fixed]
c(sameChar) = a(sameChar); % or b(sameChar)
c(~sameChar & ~isNum_a & ~isNum_b) = {'A'};

@Jan
I am wokring on the script we discussed yesterday. Now I'am making the script for more strings than two. So not only:
a = {'A'; 'B' ; 5 ; 6; 'A' ; 'A'; 'B'};
b = { 7; 'B' ;'A' ;'B'; 'A' ; 'B' ; 'A'};
But a lot more of these.
Do you have a idea how we can make the part below, if we have more strings than two.
sameChar = strcmp(a, b);
c(sameChar) = a(sameChar);
