At that point, your variable named Child is not a structure.

There is not much more we can say about the situation without more code.

You should use

dbstop if error

and then run your program. When it stops, look at size(Child) and class(Child) .

Pay attention to the possibility that you initialized

Child = [];

and then have code that you think should always assign a structure to Child: if for some reason it does not assign a structure to Child then you would encounter that error because Child would not be a structure.

the same error, but when i use dbstop if error , the error shown in Parallel cause i'm using parallel processing , so how to solve it ?

Put this line before the error and tell us what shows in the command window:

whos Child

To go beyond that we would need to see the code.
