Using Variable Contents to Create Variable names

I have two variables (RtnType and MyPG) each with their values down the rows. I would like to write the results of my code loop as I iterate through these variables to the proper variable derived by combining the values of these two variables.
RtnType = {'Daily' 'RollWeek' 'RollMonth' 'RollQtr' 'YTD' 'RollYear' 'SinceIncept'};
MyPG = {'MTAC' 'MTAM' 'MTAG' 'MLCE'};
for i = 1:4
for x = 1 to 7
MyMedian = [1.5];
%Desired Concatenation look
%MyPG{i,1} & '_' & RtnType{x,1} = [MyPG{i,1} & '_' & RtnType{x,1},[DailyMedian]
%Actual statement result for i=1 and x=1
MTAC_Daily = [MTAC_Daily; MyMedian]
end
end
Can someone show me how to write the results of each loop to different vectors that have been pre-created?
Thanks a lot, Brian

Do NOT waste your time writing bad code that creates separate variables with numbered variable names: "A frequent use of the eval function is to create sets of variables such as A1, A2, ..., An, but this approach does not use the array processing power of MATLAB and is not recommended."
Just use indexing: simple, fast, efficient, neat, simple, easy to understand, much less buggy, easier to debug, etc, etc, etc.

eval([MyPG{i} '_' RtnType{x} '= [' MyPG{i} '_' RtnType{x} ',' num2str(MyMedian) '];'])
