The error "Index exceeds Java array dimensions" occurs because MATLAB's 'javaArray' function creates Java arrays that are zero-based, whereas MATLAB uses one-based indexing. This mismatch can lead to indexing errors when accessing or assigning elements.
To create a 2D matrix where each element is a Java 'LinkedList', consider using a MATLAB cell array instead. Cell arrays are more flexible and align with MATLAB's indexing conventions.
Here's how to implement it:
n = 5;
a = cell(n, n); % Initialize a cell array
li = cell(n, n); % Initialize a cell array for iterators
for i = 1:n
for j = 1:n
a{i, j} = java.util.LinkedList(); % Create a LinkedList
li{i, j} = a{i, j}.listIterator(); % Create a list iterator
for k = 1:(i * j * n)
t = [i, j, i * j]; % Example data
li{i, j}.add(t); % Add data to the list
end
end
end
For more information on 'javaArray', refer to the following MathWorks official documentation:
This approach avoids indexing issues and integrates Java objects seamlessly within MATLAB's environment.
I hope this helps.
