dictionary in matlab in matlab

In MATLAB, the term "dictionary" is not used in the same way as it is in other programming languages. However, you can simulate a dictionary in MATLAB using structures as shown below:

main.m
% create an empty structure
my_dict = struct;

% add key-value pairs to the struct
my_dict.key1 = value1;
my_dict.key2 = value2;
my_dict.key3 = value3;

% Accessing values from the dictionary
my_dict.key1 % returns value1
my_dict.key2 % returns value2
252 chars
12 lines

Note that keys in MATLAB structures are always strings and the values can have any MATLAB data type. Also, you can use the fieldnames function to get all keys in the dictionary:

main.m
keys = fieldnames(my_dict); % returns {'key1', 'key2', 'key3'}
63 chars
2 lines

In summary, although MATLAB does not have a built-in data structure for dictionaries, structures can be used as a suitable alternative.
