get value of a dcitionary in matlab

In Matlab, a dictionary is typically represented as a struct with field names as the keys and the values corresponding to those keys stored in the field value. The value for a specific key can be accessed using either the dot notation or the cell array notation.

Here's an example:

main.m
% Define a dictionary struct
dict = struct('a', 1, 'b', 2, 'c', 3);

% Access value for key 'b' using dot notation
value1 = dict.b;

% Access value for key 'c' using cell array notation
value2 = dict.('c');

% Display the values
disp(value1);
disp(value2);
257 chars
13 lines

Output:

main.m
2
3
4 chars
3 lines

In the above code, the value for the key 'b' is accessed using the dot notation (dict.b), which directly gives us the value for that key. Alternatively, we could have used the cell array notation (dict.('b')) to achieve the same result.

Similarly, the value for the key 'c' is accessed using the cell array notation (dict.('c')).

Hope that helps!
