matlab - Indexing over all values in nested struct -

-

i have nested struct contains values , defined as:

mystruct.level1.a = 1; mystruct.level1.b = 2; mystruct.level2.a = 8; mystruct.level2.b = 9;

i want perform operations on elements in level1 , level2. want access values in level1 , level2, put them in vector, without referencing nested field names.

e.g. i'd like:

level1_vector = [mystruct.level1]

which output:

level1_vector = [1 2]

how can that?

use combination of 2 functions below:

cell2mat(struct2cell(mystruct.level1))
