What does the struct look like? What variable in the struct are you trying to get?

You can use dot indexing to get variables within a struct https://www.mathworks.com/help/matlab/ref/struct.html

% If struct "s" has fields "a", "b", "c"
myVariable = s.b; % collects the values in "b"

The struct2table function will convert the structure to a table.

Integrating it with another table depends on what the variables are and the existing table. Merging them could be anything from straightforward to impossible.

Hi osemudiamen oriabure,

I understand that you are trying to convert a struct variable to a table and then merge it with another table. You may convert a struct into a table with the help of the "struct2table" function and join with another table with the help of "join" function.

Example:

s.person=[ 'a' ,'b', 'c'];
s.height=[ 5.3, 5.11, 6.1];
t= struct2table(s);  % converting struct to table
T= join(T,t);        % T is already existing table
