Dotted names can be used only within a CLASS block.

Please provide a question to explain what you are doing and to provide context for the code. Is this your own modification of Matlab's built-in DAGNetwork class? Also, please provide code and steps that can be run by others to reproduce the error. A classdef by itself cannot be run.

I'm trying to use mobilenetv2 snd resnet50 to deep learning and I just Finish all the code and the code is fine but every time I do run for my code it is show this error and I didn't know what can I do with this error pleas I need hlep

Invalid use of operator.

Error in mobilenetv2_Results (line 136)

lgraph = layerGraph(net);

^^^^^^^^^^^^^^^

Hi @Faisal,

The error mentioned in the comments is due to the fact that the "layerGraph" MATLAB function is being overrided by your custom function.

This can be verified by running the following command in the Command Window.

which layerGraph -all

The error can be resolved by renaming or removing the custom "layerGraph.m" file from your local folder, so that MATLAB uses its built-in function instead.

It is unclear why a custom function was created for this purpose, but the issue arises because MATLAB does NOT support dotted class names like "DAGNetwork.layerGraph" unless they are defined within a package or as nested classes.

Hope this helps!
