Comparing matrices and filling in the gaps

So,
I've got two matrices
a = [A;B;C;D;E;F]; %% The entire list of variables
b = [B;D;F, 5;13;6]; %% A set of data with missing variables and amounts of occurances in second coulmn
How can i get something that gives me something like this...
c = [A;B;C;D;E;F, 0;5;0;16;0;6]

That is not a table of strings, but a cell array of char arrays. These specifics matter. It also isn't valid Matlab syntax, as you have only 1 char array on the first line, and two on the second line.
Please provide correct examples for a and b. We will probably be able to help your create something. The ismember function or the containers.Map data type might be what you're looking for.

There are just so many things you can do with joins:
>> a = table(["A";"B";"C";"D";"E";"F"]);
>> b = table(["B";"D";"F"], [5;13;6]);
>> outerjoin(a,b,'Key','Var1','Type','left','RightVariables','Var2')
ans =
6×2 table
Var1 Var2
____ ____
"A" NaN
"B" 5
"C" NaN
"D" 13
"E" NaN
"F" 6
