Hi, i have a structure which has the number of field values depending on the blobs it identifies. But, in some the frames, i run my algorithm to identify hidden blobs. Now, i need to update the field of my structure with the values of newly found blobs. eg if i have a field named "Area" and i find that its values in a certain frame are 34,36,40,39 and in another frame i find that 34,36,79. This means that the 78 blob is combined with 2 blobs. So my algorithm separates the blobs but now i need to update my structure with the new values.
Any help would be highly appreciated.

You can access the field with
mystruct.Area
So why can't you just update the field
mystruct = struct('Area',[34 36 40 39]);
mystruct.Area = [34 36 79];
If the problem is more involved than that, please include a small code example to illustrate the error.
