Not sure if this is what you are really asking:

mystruct.field1 = rand(1,3);  % <-- Create a structure with field named field1
mystruct.field2 = rand(1,3);  % <-- Add a new field2 to the existing structure

Thanks! Actually this is our specific problem: We have a structure GRF.AdDB.Gait Now we want to add a field 'time', and the result has to be GRF.AdDB.Gait.time

Just assign something to it. Like

GRF.AdDB.Gait.time = datestr(now);

Thanks, But unfortunately we tried this and it doesn't work...

Define "doesn't work". If it threw an error, show the full and exact text of the error message (don't omit anything, don't paraphrase) and show the size and class of GRF, GRF.AdDB, and GRF.AdDB.Gait. If it issued a warning, do the same as above but with the warning message instead of the error message.

Here's proof it works:

Joran, tell us what "doesn't work" means. This link might help
