Answer 1

[Azzi Abdelmalek]

I guess you are using for example a variable y.field1 where field1 does'nt exist

Answer 2

Stop Matlab, when the error occurs:

dbstop if error

Now run the function again. When it stops, check the values of the variables. The error messages means, that you try to access a field of a variable, which is not a struct.
