Do not do this! This will only lead to headaches downstream in your code for processing these variables (you will need to use more eval( ) statements etc) and will be a nightmare to debug. There are much better alternatives. E.g.,

MATLAB: All index values expect certain indices

A = [5 6 7 8];
x{1} = [1];
x{2} = [1 2];
x{3} = [2 3 4];
c = cellfun(@(i) A(setdiff(1:end,i)), x, 'unif', 0)
c{:}

That gives:

ans =
     6     7     8
ans =
     7     8
ans =
     5
