Is it possible to merge structs that are not the same size?

Is it possible to merge structs that are not the same size and have different names?

[Walter Roberson]

... Yes, if you define what should happen in each case. One of the questions is what to do if the field names are the same.

There is no structure merge function provided by Mathworks.

Sometimes it is easiest to use struct2cell and manipulate and cell2struct back.
