create structure and take the fieldnames from an array in matlab

To create a structure and take the fieldnames from an array in MATLAB, you can use the following code:

main.m
% Create an example array of fieldnames
fieldsArray = {'field1', 'field2', 'field3'};

% Create an empty structure 
myStruct = struct();

% Loop through the fieldsArray and add fields with dynamic names to the structure
for i = 1:length(fieldsArray)
    fieldName = fieldsArray{i};
    myStruct.(fieldName) = [];
end

In this code, we first create an example array named "fieldsArray" which contains the fieldnames we want for our structure.

Then, we create an empty structure named "myStruct" using the "struct()" function.

Finally, we loop through the "fieldsArray" and add fields to "myStruct" with dynamic names using the dot notation syntax. We use the current fieldname in each iteration (stored in the "fieldName" variable) to define a new field with that name in the structure.

Note that we initialize each field to an empty value in this example, but you can set it to any value or expression you need.
