dictionary with array as value in matlab

A dictionary, also known as a map, is a data structure that allows you to store values with corresponding keys for fast lookup. In MATLAB, you can create a dictionary with an array as value using containers.Map class.

Here is an example of how to create a dictionary with a cell array as value and access its elements:

main.m
% Create a dictionary with cell array as value
my_dict = containers.Map;
my_dict('key1') = {'value1', 'value2', 'value3'};
my_dict('key2') = {'value4', 'value5', 'value6'};

% Accessing values in dictionary
my_dict('key1')    % Returns {'value1', 'value2', 'value3'}
my_dict('key2'){2} % Returns 'value5'
305 chars
9 lines

In the example above, we first create an empty dictionary my_dict with containers.Map. We then add values to the dictionary using the syntax my_dict('key') = value;, where 'key' is the lookup key and value is the value to be associated with that key. We use a cell array to store multiple values for each key.

To access the values in the dictionary, we use the syntax my_dict('key') to retrieve the cell array associated with the given key. We can then access individual elements of the cell array using curly braces {}.

Note that the elements in the cell array can be of different types, such as strings, numbers or other cells.
