How to form a structure array variable?
显示 更早的评论
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!

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})

Simpler using indexing:
vec = {'a','b','c'};
Test{1}.(vec{Ind})
