Access Data Within Structure Array

Hello,

I'm new to Structure Arrays, but believe it is what I'm looking for to help me with my script after reading advice to not dynamically name variables.

One question I had: If I have data like this:

g = [1,3,5];

A = [90 89 88 87];
B = rand(4,2);
C = 70;

s.a = g;
s.b = {A,B,C};

I understand if I want to access the second datapoint of g, I'd type:

s.a(2)

Which will give me '3'.

Let's say I want to access the number 89 within A through the Structure.

This gives me the whole A array:

s.b(1)

But is there something like this, where I can get the 89 directly?

s.b(1(2))

This doesn't work, but I'm trying to get the second number (89) of the first variable (A) within s.b.

Or can I not do this?

Thanks.

There is a way

g = [1,3,5];

A = [90 89 88 87];
B = rand(4,2);
C = 70;

s.a = g;
s.b = {A,B,C};
val=cellfun(@(x) x(2), s.b(1))

ans = 89

g = [1,3,5];
A = [90 89 88 87];
B = rand(4,2);
C = 70;
s.a = g;
s.b = {A,B,C};

s.b{1}(2)

ans = 89
