Error is occured when I changed version of Matlab

I have a lot of the code which work correctly in the Matlab 2013b but when I tried evaluate it on the machine with Matlab 2016a it returns an error:

Too many outputs requested.  Most likely cause is missing [] around left hand side that has a comma separated list expansion.

Line with an error is next

L.GroundWire(i).(FN{j})=GroundWire.(FN{j}){ISb};

where

ON LEFT

L - object of user-defined class

GroundWire - property of L, structure

FN{ j } - name of field of GroundWire

ON RIGHT

GroundWire - structure

FN{ j } - name of field. each field consists of cells with data

ISb - integer number

What have changed in the new version of Matlab?

I can add that if I contain the expression on the left in braces it causes an another error in both versions of Matlab.

Simplest way to find out is with the debugger, just put

GroundWire.(FN{j}){ISb}

on the command line and see what the result is. You can also try putting the left-hand side on the command line too:

L.GroundWire(i).(FN{j})

and see what it evaluates to.

I guess, that ISb is not a scalar. Test this using the debugger: https://www.mathworks.com/help/matlab/matlab_prog/debugging-process-and-features.html. If this is true, this might help:

L.GroundWire(i).(FN{j}) = [GroundWire.(FN{j}){ISb}];

But most likely ISb is not expected to address multiple cell elements, such that the actual problem must be before this line while creating ISb.

Seems to be truth if another functions changed and ISb became an array but I didn't find real cause for this error.

Thanks.
