How do I access properties of objects embedded inside another object organized in an array?

I have created two classes, an 'inner' and 'outer' class. The 'outer' class has properties defined by methods that depend on data from the 'inner' class. I want to access properties for an array objects from the 'inner' class embedded inside an array of 'outer' class objects. I have tried indexing using various methods to no avail.
For example, I have 10 'outer' objects with 3 'inner' objects embedded within each. If I want to simultaneously define a value for a property of the array of 30 'inner' objects, I cannot. I have tried:
outer_obj(:,1).inner_obj(:,1).inner_property = value
but am getting an error. I haven't seen documentation that provides guidance on how to assign values to properties of an array of objects that are embedded inside an array.
Any assistance is greatly appreciated.

Is this the error message you see?
Expected one output from a curly brace or dot indexing expression,
but there were 2 results.
"I haven't seen documentation that provides guidance ... "
  • Why do you think it is possible?
  • What's not found in the documentation is typically not implemented!

% build an empty struct
A = struct;
A.outer = struct;
% either fill it
for i = 1:10
for j = 1:3
A(i,1).outer(j,1).inner = [i,j];
% or make it homogeneous
val = 'homogeneous input'
for i = 1:10;
for j = 1:3
A(i,1).outer(j,1).inner = val;
