clearing an instance of a structure variable

hello!

I was wondering whether it is possible to clear an instance on a structure variable, as in the following example.

a = struct('name',0,'age'',0)

a(1) = struct('name','jack','age',20);
a(2) = struct('name','fred','age',28);

So my question would be: is there a way to clear either a(1), for instance, such that the final length of 'a' becomes 1, instead of 2?

You can remove an element from a structure array the same way you can remove an element from any other type of array:

a(1) = [];  % Set the first element to empty

Or:

a = a(2);  % Index the second element and reassign it to a

a = a(2)
