MATLAB: Does this variable exist

Question

Hello,

Is it possible to check if a sub variable of a variable existing in the workspace exists?

For exemple 'layers' variables exist in the workspace, how can I put a condition on the existance of layers(k).Weights ?

I know that exist('layers','var') is used to check the existance of variables in workspace.

Thank you! Appreciate any help!
