add new fieldname to structure in matlab

To add a new field name to an existing structure in MATLAB, you can use the dot notation and assign a value to the new field name. Here's the syntax:

main.m
structure.fieldname = value;
29 chars
2 lines

For example, suppose you have a structure called "my_struct" with two fields, "name" and "age". To add a new field called "email" with the value "john.doe@email.com", you can do the following:

main.m
my_struct.email = 'john.doe@email.com';
40 chars
2 lines

After executing this line of code, "my_struct" now has three fields: "name", "age", and "email".
