loop or other better solution for mixing?

Hello, I want to do some mixing and wonder if there is any better solution other than looping.
I want to mix any number of ingredients to make one solution. The total percentage of the ingredients added up should equal to 100%. The percentage of each ingredient can be from 0% to 100%. I need to go through and save all the possible compositions with distinct names, and do calculations in order to find out the best composition.
Starting with two databases A and B, each with 4 columns of numerical data. I will need to produce and save all the mixed combination. For example, 10% of each column in A add 90% of the corresponding column in B, and save the result. The total percentage is 100%. This could be done with loop. x=0:0.1:1, C=x*A+(1-x)*b. This seems straightforward, if I only have two databases A and B.
If I have three databases, A, B and C, to produce D. So I need two loops?
If I have A, B, C and D, to produce E, so I need to have three loops?
If I want to mix more, do I have to create another loop again?
As the number of the databases I want to mix increase, this looping solution seems inefficient. Because everytime the numer of database changes, I need to rewrite my code again.
I was wondering if there is any better solution for this problem. So it does not need me to redo the coding even if I change the number of databases to be mixed. I hope I only need one code to run whatever number of databases that I want to mix.
I tried the following for two components and it did not work:
data1=importdata('\rawdata1.txt');
data2=importdata('\rawdata2.txt');
for x = 0:10:100, y = 0:10:100 & x+y=100;
data = data1.*x + data2.*y;
folder = '\Desktop\';
filename = sprintf('data_component1_%d_component1_%d.xls', x, y);
fullfilename = fullfile(folder, filename);
xlswrite(fullfilename, data);
end
Can someone help? Thank you very much.

Write matlab function with the "varargin" argument. See matlab documentation on it.
