Hi all friends
I have a structure variable; this variable is defined as follows:
Student structure; consists of the following fields
Name
Age
Suppose that I fill it with data (for example five students)
Later I want to add another field (for example degree field) to student structure
How can I do that and fill the degree field with data
Please help me

teststruct = struct('names',{'bob','dave','sara'});
% now add field called data
[teststruct(:).data] = deal(randn(3,1));

C = num2cell(randn(3,1));
[teststruct(:).data] = deal(C{:})
How this works is explained in the MATLAB documentation:
