creating a dictionary with an array as value in matlab without containers.map in matlab

In MATLAB, you can create a dictionary (associative array) with an array as a value by using cell arrays. Cell arrays are suitable for storing heterogenous data types, including arrays.

Here's an example of how you can create a dictionary-like structure using cell arrays:

main.m
% Initialize an empty cell array
myDict = {};

% Adding key-value pairs to the dictionary
key1 = 'Key1';
value1 = [1,2,3];
myDict{end+1} = {key1, value1};

key2 = 'Key2';
value2 = [4,5,6];
myDict{end+1} = {key2, value2};

% Accessing values using keys
for i = 1:numel(myDict)
    key = myDict{i}{1};
    value = myDict{i}{2};
    
    disp(['Key: ', key]);
    disp(['Value: ', num2str(value)]);
end
400 chars
21 lines

In this example, the myDict cell array stores each key-value pair as a cell array within it. Each cell array has two elements: the key and the corresponding array value.

To retrieve a value from the dictionary, you can iterate over the myDict cell array and compare the keys.

Note that MATLAB also provides the containers.Map data structure for easily creating dictionaries. However, if you specifically want to avoid using containers.Map, the cell array approach described above can be used as an alternative.
