MATLAB: How to form a structure array variable

Question

I have a structure array like the below

Test{1}.a = [1; 2; 3];
Test{1}.b = [7; 3; 22];
Test{1}.c = [4; 9; 22];
...

If I have a variable (Var) that can be either a, or b, or c, …

If Ind == 1;
    Var = 'a';
elseif Ind == 2
    Var = 'b';
elseif Ind == 3
    Var = 'c';
end

How do I specify Test{1}.Var, so that when Ind == 1, it will be Test{1}.a, and so on?

Many thanks!

Answer 1

See Steven Lord's reply here. Basically, something like this:

Test{1}.a = [1; 2; 3];
Test{1}.b = [7; 3; 22];
Test{1}.c = [4; 9; 22];
Ind = 2;
if Ind == 1
    Var = {'a'};
elseif Ind == 2
    Var = {'b'};
elseif Ind == 3
    Var = {'c'};
end
Test{1}.(Var{1})
ans = 3×1
     7
     3
    22
