Creating matrix of unique combinations of variables

I need to create a matrix that lists out each combinations of variables in each row.

Assume that I have 5 variables a1, a2, a3, a4, a5 that all have 10 possible values of 0.1:0.1:1, what is an elegant way to list out the 10^5 rows of combinations?

Thank you so much!

 nvals = 5;
 [a{1:nvals}] = ndgrid(0.1:0.1:1);
 Result = cell2mat(cellfun(@(C) C(:), a, 'Uniform', 0));

Hi, it would be nice to have some code to work with included. But this is actually thing you would easily solve with MatLab help. Look at perms function. Input is your data and output is array of all possible combinations.
